2.6 Observation Techniques and Assessment Across Curricular Areas

The Three Observation Techniques Named in the Framework

Objective 0003 asks candidates to apply knowledge of "observation techniques (e.g., anecdotal, frequency, temporal)." Each answers a different question, and choosing the wrong one produces data that cannot support a decision.

1. Anecdotal (Narrative) Recording

The observer writes a running, objective description of everything the student does and everything that happens around them during a defined period, without categories decided in advance.

• Question it answers: What is actually going on here?
• Use it when: the behavior is not yet understood, the referral concern is vague, or the team needs to generate hypotheses. It is the natural precursor to an ABC analysis, because the antecedent-behavior-consequence structure is extracted from the narrative after the fact.
• Discipline required: record observable events only. "Student slid down in the chair, put head on desk, and did not pick up a pencil for four minutes after the worksheet was distributed" is anecdotal data. "Student was unmotivated" is an inference.
• Limitation: not quantitative, vulnerable to observer selection, and cannot show change over time.

2. Frequency (Event) Recording

The observer counts discrete occurrences of an operationally defined behavior within a set period, and converts to a rate (occurrences per minute or per hour) whenever observation periods differ in length.

• Question it answers: How often?
• Use it when: the behavior has a clear beginning and end and occurs at a moderate rate — hand raises, call-outs, throws, requests for help.
• Do not use it when: the behavior is continuous (humming, rocking) or extremely high-rate, because counts become unreliable.
• Reporting rule: always report rate, not raw counts, when comparing across days. Twelve call-outs in 20 minutes and twelve in 60 minutes are very different findings.

3. Temporal Recording

"Temporal" covers the family of methods that measure behavior against time rather than counting instances:

The two directional biases are heavily tested: partial-interval inflates, whole-interval deflates. Choose deliberately — whole-interval is conservative and therefore appropriate for engagement goals, while partial-interval is appropriate when you need to be sure a dangerous behavior is captured.

Scatterplot Recording

A scatterplot grids time of day against days of the week and records whether the behavior occurred in each cell. It answers when and where, and it is the fastest way to reveal that a behavior is concentrated in unstructured transitions or in one subject — information that antecedent interventions can act on immediately.

Assessing Across All Curricular Areas

Objective 0003 requires knowledge of "methods and strategies for assessing students' skills within curricular areas, including academic, social-emotional, functional, and transition." IDEA defines educational performance to include functional performance, and Illinois defines it to include the ability to establish and maintain social relationships and to experience sound emotional development. An assessment that reports only reading and math levels is incomplete.

Academic

Combine norm-referenced achievement (for eligibility comparison), criterion-referenced and curriculum-based measures (for instructional planning and progress monitoring), error analysis of work samples (to isolate the breakdown point — is the math failure computational, procedural, or a reading-the-problem failure?), and diagnostic probes such as phonological awareness or place-value checks.

Social-Emotional

Use behavior rating scales completed by multiple informants across settings, student self-report (essential for internalizing concerns, which adults under-detect), sociometric or peer-relationship data, direct observation in structured and unstructured settings, and review of office discipline referrals, attendance, and nurse visits. Setting-specific disagreement between informants is data, not noise.

Functional and Adaptive

Standardized adaptive behavior scales such as the Vineland-3 or ABAS-3 give a normative picture, but the instructional tool is the ecological inventory and the discrepancy analysis that follows it:

1. Identify the domain (school, home, community, vocational, recreation/leisure).
2. Identify the environment and then the specific subenvironment (the school; the cafeteria).
3. List the activities required there (get a tray, pay, select a seat, clean up).
4. Task-analyze each activity into steps a person without a disability performs.
5. Conduct a discrepancy analysis: watch the student do it, mark each step as independent or not, and diagnose why a failed step failed — skill deficit, motor limitation, communication barrier, or missing adaptation.
6. Decide, step by step, whether to teach the skill or to provide an adaptation (an alternative performance strategy such as a picture card, a preloaded payment account, or partial participation).

This process produces goals that are demonstrably functional, because every step came from an activity the student actually has to perform.

Transition

Age-appropriate transition assessment is required and must be ongoing. It combines formal interest inventories and aptitude batteries, adaptive and independent-living scales, situational assessment at real community job sites, structured student and family interviews about preferences and postsecondary vision, and self-determination measures. The output feeds the three postsecondary goal areas directly. In Illinois this must be underway no later than the IEP in effect when the student turns 14½.

Adapting the Environment and Administration Without Losing Validity

Objective 0003 also asks candidates to apply knowledge of "principles and procedures for adapting the environment and administering informal and formal assessments." The governing rule is the construct being measured:

• Environmental adaptations are almost always safe: quiet room, reduced visual clutter, preferential positioning, adaptive seating, adequate lighting, scheduled breaks, testing at the student's optimal time of day relative to medication.
• Access adaptations are safe when they remove a barrier unrelated to the construct: a scribe for a student with a graphomotor impairment on a science test, sign language interpretation of directions, enlarged print, an AAC device for responding.
• Adaptations that change the construct invalidate the score: reading a decoding or reading-comprehension test aloud, providing a calculator on a computation test, giving extended time on a test whose norms are built on a fixed speeded administration, or rewording items on a standardized instrument.

When a needed adaptation would breach standardization, the correct move is not to abandon the assessment but to administer it in the standard way, then retest with the adaptation as a supplementary, descriptive procedure, and report the nonstandard result narratively while clearly labeling it as invalid for normative comparison. Every deviation from standardization must be documented in the evaluation report.
