Unit 3: Assessment of Language

Assessment: Meaning, Definition & Scope

Traditional Oralism (often called the Auditory-Oral approach) allowed and even encouraged the use of speechreading (lip-reading) alongside listening. The Auditory-Verbal Approach (AVA) strictly removes the visual cues. It focuses exclusively on the auditory channel to force the auditory cortex of the brain to wire itself for sound.

For infants and young children with hearing loss to grow up in regular learning environments, attend mainstream schools, and become independent, fully participating citizens in mainstream society.

AVT is based on the premise that the brain’s auditory pathways must be stimulated early (before age 3). If the brain is fed clear, amplified sound via Cochlear Implants or Hearing Aids, it will physically restructure itself to understand spoken language.

Principles of the Auditory-Verbal Approach

The Alexander Graham Bell Academy outlines strict guiding principles that define certified AVT. The most critical for an educator to know are:

1. Early Diagnosis & Immediate Amplification: Detect hearing loss as early as possible (newborn screening) and immediately fit the child with the most aggressive, appropriate technology (Cochlear Implants or high-powered Hearing Aids) to achieve maximum acoustic access to the “Speech Banana.”
2. Parent as the Primary Therapist: This is the most radical departure from traditional therapy. AVT is a parent-coaching model. The therapist does not “treat” the child; the therapist coaches the parents on how to turn everyday routines (bathing, eating, playing) into listening environments.
3. Auditory-First: Guide the child to use hearing as the primary sensory modality. Therapists actively teach parents to sit beside or behind the child (rather than face-to-face) to prevent lip-reading, forcing the brain to rely on sound.
4. Natural Voice: Speak in a natural speaking voice with natural prosody (rhythm and melody). Do not use exaggerated, robotic, or overly loud speech.
5. Mainstreaming: Continually assess the child’s progress to ensure they are on track to enter a regular, mainstream classroom alongside their hearing peers.

Pre-requisites for the Auditory-Verbal Approach

AVT is highly effective, but it is not magic. It requires a strict set of conditions to be successful. If these pre-requisites are not met, the child is at high risk of language deprivation.

A. Audiological Pre-requisites

• Maximum Acoustic Access: The child must be able to hear all frequencies of conversational speech. If a child’s hearing aids are not powerful enough to give them access to high-frequency consonants (like /s/ or /sh/), AVT will fail. They must have optimal, well-maintained technology.
• Consistent Device Wear: “Eyes open, ears on.” The brain requires constant auditory stimulation to build neural pathways. Devices must be worn all waking hours.

B. Cognitive Pre-requisites

• Intact Central Processing: The child must have the baseline cognitive capacity to process information, store it in working memory, and execute means-end behavior. (Children with severe additional cognitive disabilities may require visual supports alongside AVT).

C. Environmental and Family Pre-requisites

• Massive Parent Commitment: Because AVT is a coaching model, the parents must have the time, emotional bandwidth, and dedication to practice listening strategies constantly at home.
• Favorable Acoustic Environment: A home environment where background noise (TVs, radios, loud fans) is minimized so the child gets a clear “signal-to-noise ratio” when the parent is speaking.

Stages of Auditory-Verbal Therapy

While AVT aligns with Erber’s Hierarchy of listening (Awareness, Discrimination, Identification, Comprehension), in an AVT clinic, these stages are integrated directly into natural play and spoken language development.

Stage 1: Auditory Awareness & Attention (0-6 Months Auditory Age)

• The Focus: Teaching the brain that sound exists and has meaning.
• The Strategy: The therapist teaches the parent to use the “Listen!” prompt. The parent points to their ear, looks excited, and presents a sound (like a knock on the door or a toy drum). The child is conditioned to respond to the presence of sound.

Stage 2: Sound-Object Association (6-12 Months Auditory Age)

• The Focus: Attaching specific acoustic patterns to objects using Learning to Listen (LTL) Sounds. These are vowels and consonants paired with toys (e.g., “Ahhh” for an airplane, “Mooo” for a cow, “P-p-p” for a boat).
• The Strategy: Using Acoustic Highlighting. The parent sings or emphasizes the target sound to make it stand out against background speech.

Stage 3: Language Comprehension / Identification (1-2 Years Auditory Age)

• The Focus: Building receptive vocabulary using an auditory-only signal. The child must understand words without seeing the object or the speaker’s mouth.
• The Strategy: The Auditory Sandwich (Listen-Look-Listen). The parent says, “Get your shoes.” If the child doesn’t understand, the parent points to the shoes (Look), but then immediately removes the visual cue and says it again (Listen) to re-center the brain on the sound.

Stage 4: Advanced Comprehension and Expressive Language (2+ Years Auditory Age)

• The Focus: Following multi-step directions, answering abstract questions, and using complete syntax and grammar to hold a conversation.
• The Strategy: Sabotage and Wait Time. The parent deliberately gives the child a bowl of soup without a spoon, leans in, and uses expectant “Wait Time” to force the child to formulate the spoken request: “I need a spoon.”

Pedagogical Implication

As a special educator, the most important takeaway is that AVT is a mindset, not just a curriculum. It is the belief that if you provide the brain with access to sound and train the parents to be the primary communicators, deafness becomes a technological hurdle rather than an absolute barrier to spoken language.

The AVT Parent-Coaching Model

To understand why AVT is a “new trend” compared to historical oralism, you must visualize the shift in power. The therapist does not fix the child; the therapist empowers the parent.

The “New Trend” in Oralism

Informal Assessment: Importance, types and documentation

While formal assessment tells you if a student has a disability, informal assessment tells you how that disability impacts their daily life and what you need to teach them today.

Importance of Informal Assessment

Informal assessment is the backbone of daily special education. Its critical importance lies in addressing the blind spots of standardized testing:

• Ecological Validity: Standardized tests measure a child in an artificial, quiet clinic. Informal assessments measure the child in their actual ecosystem (the noisy classroom, the cafeteria, the playground), showing true functional performance.
• Cultural and Linguistic Fairness: It eliminates the cultural bias found in standardized tests. You can assess a child using materials, vocabulary, and routines they are actually familiar with from their home life.
• Informs the IEP Directly: Standardized scores (like a “72”) do not tell you what to teach. Informal assessments identify the exact missing splinter skills needed to write actionable Individualized Education Program (IEP) goals.
• Low Anxiety: Because these assessments are integrated into natural play or daily routines, the child rarely experiences “test anxiety,” resulting in a more accurate reflection of their abilities.

Types of Informal Assessment

Educators use a variety of tools to gather a complete picture of the student.

• Naturalistic Observation: * What it is: Passively watching the student in their environment without interfering.
  • Best for: Assessing social skills, pragmatic language (how they talk to peers), and behavioral triggers.
• Criterion-Referenced Checklists / Developmental Scales:
  • What it is: A pre-determined list of skills. The educator checks “Yes,” “No,” or “Emerging.” It compares the child to a skill, not to other children.
  • Best for: Tracking specific academic milestones (e.g., “Can identify 10 sight words,” “Can cut with scissors”).
• Portfolio Assessment:
  • What it is: A curated collection of the student’s actual work over time (e.g., writing samples from September, January, and May).
  • Best for: Visually demonstrating longitudinal progress to parents during IEP meetings.
• Interviews and Questionnaires:
  • What it is: Gathering qualitative data from parents, past teachers, or the student themselves.
  • Best for: Understanding the child’s behavior at home, identifying their personal interests (to use as rewards), and gathering family history.
• Dynamic Assessment (Test-Teach-Retest):
  • What it is: An interactive assessment to measure a child’s learning potential. You test a skill, provide direct coaching/scaffolding, and then test again to see how quickly they absorbed the instruction.
  • Best for: Differentiating between a true language disorder and a simple lack of prior educational exposure.

Documentation: The Golden Rule of Objectivity

Because informal assessments lack standard statistical scores, their legal and clinical validity depends entirely on the educator’s ability to document them objectively.

Fact vs. Inference You must never document your feelings or assumptions about why a child did something. You must act like a video camera, recording only what can be seen and heard.

• Subjective (Wrong): “Aarav was being lazy and refused to read.” (You cannot measure ‘lazy’).
• Objective (Right): “When handed the reading book, Aarav put his head on his desk and did not open the book for 5 minutes.”

The ABC Data Collection Model When documenting informal behavioral or communicative observations, educators universally use the ABC model to find the function (the “why”) of the behavior:

1. A – Antecedent: What happened in the environment immediately before the behavior? (e.g., The fire alarm went off).
2. B – Behavior: What exactly did the child do? (e.g., The child covered their ears and hid under the desk).
3. C – Consequence: What happened immediately after? (e.g., The teacher evacuated the child to a quiet zone).
   • Takeaway: The data shows the behavior was an informal communication of sensory overload, and the consequence provided an escape.

Choosing the Right Assessment Tool

A skilled special educator must know exactly which informal tool to pull from their toolkit based on the clinical question they are trying to answer.

Use the interactive simulator below to practice matching common classroom and clinical scenarios to the most appropriate type of informal assessment.

Teacher Made Test (TMT): Development & implementation

While standardized tests are the massive, generic ships of the assessment world, the Teacher-Made Test is the agile speedboat. For a general or special educator, TMTs are the daily bread-and-butter used to track immediate progress, adapt instruction, and measure specific Individualized Education Program (IEP) goals.

What is a Teacher-Made Test?

• Definition: A Teacher-Made Test is an assessment instrument developed by a classroom teacher to measure how well their specific students have learned a specific unit of instruction taught in their specific classroom.
• The Core Purpose: Unlike standardized tests (which compare students to a national average), a TMT is usually criterion-referenced. It asks, “Did my students actually learn what I just taught them this week?”
• Flexibility: TMTs can take any form: written quizzes, oral exams, practical demonstrations, or matching worksheets.

Importance and Justification

Why do teachers spend hours writing their own tests when textbooks provide pre-made ones?

• Perfect Alignment: A textbook test might cover a chapter section you skipped. A TMT tests exactly what was covered in class, matching the teacher’s unique emphasis and pace.
• Immediate Feedback: TMTs allow educators to quickly identify learning gaps. If 80% of the class fails a TMT on Tuesday, the teacher knows to reteach the concept on Wednesday.
• Differentiation (Crucial for Special Education): TMTs can be customized for different reading levels, visual needs, or cognitive abilities within the same classroom, making them highly equitable.

The 4 Stages of TMT Development

Creating a highly effective, fair test is a scientific process. Poorly made tests measure a student’s ability to guess, not their actual knowledge.

Stage 1: Planning and Weightage

Before writing a single question, the teacher must decide what matters most.

• Weightage to Content: If you spent 3 weeks teaching Addition and 1 week teaching Subtraction, the test should be 75% Addition questions and 25% Subtraction questions.
• Weightage to Objectives (Bloom’s Taxonomy): A good test measures different levels of thinking. A test should not be 100% rote memorization. It must include:
  • Knowledge: Recalling facts (e.g., “Define noun.”)
  • Understanding: Explaining concepts (e.g., “Give an example of a noun.”)
  • Application: Using knowledge (e.g., “Circle the nouns in this sentence.”)
• Weightage to Form of Questions: Deciding the mix of Objective items (Multiple Choice, True/False) and Subjective items (Short Answer, Essay).

Stage 2: Preparing the Blueprint (Table of Specifications)

• What it is: A Blueprint is a 2D grid or chart that maps the Content (topics) against the Objectives (Bloom’s Taxonomy).
• Why it matters: It prevents the teacher from accidentally writing a test that is completely unbalanced (e.g., 20 memorization questions on one tiny topic and zero application questions on the main topic). It is the architectural plan of the test.

Stage 3: Drafting the Items (Question Writing)

The actual writing of the test. Key rules include:

• Keep language simple and unambiguous. Avoid “trick” questions.
• For Multiple Choice, ensure all distractors (wrong answers) are plausible. Avoid “All of the above” or “None of the above” as they often confuse students unnecessarily.
• Group similar item types together (e.g., put all True/False together, all Matching together) to reduce cognitive switching fatigue.

Stage 4: Assembling, Formatting, and Instructions

• Provide crystal-clear instructions at the top of the page.
• Ensure adequate physical space for students to write their answers.
• Review: Ideally, let another teacher read the test to spot confusing wording before giving it to students.

Implementation and Administration

Administering the test in a way that minimizes anxiety and maximizes performance.

• Physical Environment: Ensure good lighting, adequate spacing between desks to prevent cheating, and a quiet room.
• The “Testing Climate”: Frame the test as an opportunity to show what they know, not as a punishment.
• Accommodations (The IEP Reality): In special education, implementing the TMT requires strict adherence to legal accommodations:
  • Time: Providing extended time (e.g., time-and-a-half).
  • Setting: Allowing the student to take the test in a quiet resource room.
  • Format: Reading the questions aloud to a student with dyslexia, or allowing a student with dysgraphia to answer orally instead of writing.

Limitations of Teacher-Made Tests

While essential, TMTs have significant blind spots:

• Questionable Reliability: Because they are not statistically tested on thousands of students, TMTs often contain flawed questions, ambiguous wording, or inconsistent grading rubrics.
• Subjectivity: Essay and short-answer questions are highly prone to teacher bias during grading (e.g., grading a student with neat handwriting higher than one with messy handwriting, regardless of content).
• Limited Scope: They cannot tell a teacher how their students are performing compared to other schools in the district or state.
• Time-Consuming: Designing a mathematically balanced, fair Blueprint and drafting excellent questions takes a massive amount of unpaid planning time.

Pedagogical Implication (For the Special Educator)

For a special educator, the TMT is not just an exam; it is IEP data. If a student’s IEP goal is “Will identify 10 sight words with 80% accuracy,” you cannot wait for the state’s end-of-year standardized test to check. You must design a specific, targeted TMT (like a flashcard checklist) to track that exact data point weekly or monthly.

The Test Blueprint Builder

The most common mistake new teachers make is skipping the Blueprint (Table of Specifications). They just sit down and write whatever questions pop into their head, usually resulting in a test that only measures rote memorization.

Use the simulator below to build a Test Blueprint. Notice how distributing questions across Bloom’s Taxonomy forces you to create a fairer, deeper assessment.

Basic Language Competence: Concept & use in assessing specific language aspects

Basic Language Competence refers to a child’s foundational ability to understand (receptive) and produce (expressive) language to communicate their basic needs, interact socially, and comprehend everyday instructions.

• The Functional Baseline: It is the minimum threshold of linguistic skill required to navigate daily life without constant adult translation or intervention.
• BICS vs. CALP (Cummins’ Framework): In educational linguistics, Basic Language Competence is often equated with BICS (Basic Interpersonal Communicative Skills)—the conversational, playground language that takes 1 to 3 years to develop. This is distinct from CALP (Cognitive Academic Language Proficiency)—the formal, textbook language required to write an essay, which takes 5 to 7 years to master.
• The “Whole” vs. The “Parts”: Competence is not just having a large vocabulary. A child with Autism might have the vocabulary of an adult (high semantics) but be unable to use those words to ask for a glass of water or say hello (low pragmatics).

The Framework: The Five Aspects of Language

To assess language competence, educators divide language into three broad categories containing five specific domains. A deficit in any of these domains results in a breakdown of overall competence.

A. FORM (The Structure)

1. Phonology: The rule system governing speech sounds. (e.g., Knowing that the sound /ng/ never starts a word in English).
2. Morphology: The rule system governing the internal structure of words and how to alter their meaning using prefixes/suffixes. (e.g., Adding “-ed” to walk makes it past tense).
3. Syntax: The rule system governing how words are combined into grammatical sentences. (e.g., English uses Subject-Verb-Object: “The boy hit the ball”).

B. CONTENT (The Meaning) 4. Semantics: The rule system governing the meaning of words and word combinations. This includes vocabulary, synonyms, antonyms, and multiple-meaning words.

C. USE (The Social Context) 5. Pragmatics: The rule system governing how language is used for social purposes. This includes taking turns, making eye contact, understanding sarcasm, and adjusting language for different listeners (e.g., talking to a baby differently than talking to a principal).

Use in Assessing Specific Language Aspects

When a student struggles with basic competence, the educator must conduct a Language Sample Analysis (recording the child speaking naturally for 10-15 minutes) or use formal testing to isolate exactly which domain is impaired. Here is how specific aspects are assessed:

Assessing Phonology

• The Assessment Question: Can the child correctly perceive and produce the sounds of their language?
• How it is Assessed: Having the child name pictures to see if they substitute, omit, or distort sounds.
• Marker of Incompetence: A 5-year-old who says “tat” instead of “cat” (fronting) or leaves off the ends of all words (“cah” for “cat”).

Assessing Morphology

• The Assessment Question: Is the child using grammatical markers correctly for their age?
• How it is Assessed: Calculating the MLU (Mean Length of Utterance). The educator counts how many morphemes (units of meaning) the child uses per sentence. “Dogs” is one word, but two morphemes (Dog + plural s).
• Marker of Incompetence: A 4-year-old who says “Two shoe” instead of “Two shoes” or “He walk yesterday” instead of “He walked.”

Assessing Syntax

• The Assessment Question: Can the child organize words into a logical, rule-based sequence?
• How it is Assessed: Asking the child to describe an action picture or follow multi-step directions.
• Marker of Incompetence: Speaking in telegraphic fragments (“Me go store”) beyond age 3, or failing to understand passive sentences (“The dog was chased by the boy”).

Assessing Semantics

• The Assessment Question: Does the child have an age-appropriate vocabulary and understand relationships between words?
• How it is Assessed: Receptive vocabulary tests (pointing to a picture when named) and expressive tests (naming the picture). Categorization tasks (e.g., “Name three fruits”).
• Marker of Incompetence: Frequently using empty placeholder words like “thing” or “stuff” because they cannot retrieve the specific noun, or not understanding basic prepositions (in, on, under).

Assessing Pragmatics

• The Assessment Question: Can the child use their language to successfully navigate social situations?
• How it is Assessed: Naturalistic observation on the playground or in group work. Checklists completed by parents or teachers.
• Marker of Incompetence: Interrupting constantly, giving zero eye contact, standing too close, or having a one-sided conversation about trains without noticing the listener is bored.

Pedagogical Implication (For the IEP)

Understanding these specific aspects is the only way to write a valid Individualized Education Program (IEP).

If you write a goal that says, “Leo will improve his language competence,” it is legally and clinically useless because it cannot be measured. By assessing the specific aspects, you write targeted goals:

• Morphology Goal: “Leo will use the regular past tense ‘-ed’ marker in spontaneous speech with 80% accuracy.”
• Pragmatic Goal: “Leo will initiate a peer interaction using a greeting 3 times per recess.”

Interactive Exploration: Clinical Language Domain Analyzer

To master the assessment of Basic Language Competence, you must learn to listen to a child’s flawed utterance and immediately diagnose which specific domain of language is breaking down.

Use the simulator below to select a clinical observation and analyze where the linguistic error occurs.
