What Are the Assessment Requirements for an Annual IEP Review in California

June 07, 2026 · 10 min read

Your annual IEP review is scheduled for next month. The team has the existing triennial report and progress data, but a teacher just flagged new difficulties with executive function. Now you need to determine whether the annual review requires a formal assessment. The annual IEP review assessment requirements California imposes are not automatic: unlike an initial or triennial evaluation, an annual review does not force a full battery. But the team must ensure it has enough current data to make sound decisions about eligibility, goals, and placement. This article covers the legal framework, when assessments are required, what assessments are typically included, and how to document the process.

Legal Framework for Annual IEP Review Assessments

The Individuals with Disabilities Education Act (IDEA) requires each IEP team to review the child's present levels of academic achievement and functional performance at least once per year. 20 U.S.C. Section 1414(d)(4) states that the IEP team must consider the child's progress toward annual goals and determine whether additional data are needed. California Education Code 56344 implements that requirement by specifying that the IEP team shall determine whether additional assessments are necessary as part of the annual review.

Unlike initial evaluations, which require a comprehensive assessment across all areas of suspected disability, or triennial evaluations (required at least every three years under Ed Code 56381), the annual review does not mandate a full battery. Instead, the team must decide based on the sufficiency of current information. The annual review can proceed with existing data if it is still valid and comprehensive. If the last triennial was completed fewer than three years ago and the data remain current, the team may rely on it.

However, the district must ensure the annual review is based on enough information to determine continued eligibility, write measurable goals, and justify the services and placement in the IEP. If the existing data are insufficient, an assessment is required. The team's decision must be documented in the meeting notes.

When Assessments Are Required at an Annual IEP Review

Several triggers can compel the team to initiate an assessment for the annual review, even if a triennial is not due.

New areas of suspected disability. If a parent or teacher reports concerns not previously evaluated, such as behavioral challenges, executive function deficits, or social emotional difficulties, the team must consider whether those areas warrant a formal assessment. Under Ed Code 56320, the district must assess in all areas of suspected disability. A new concern introduced at the annual review meeting should lead to an assessment plan if the team agrees the concern is credible and not already covered by existing data.

Insufficient current data. If the most recent triennial evaluation is more than three years old and progress monitoring data are sparse, the team cannot make an informed decision about continued eligibility. For example, a student with a specific learning disability who has not had updated achievement testing since third grade and is now entering fifth grade may need a new academic assessment to determine whether the disability still exists. The team should document the gap and issue an assessment plan.

Change in placement or services. A significant change, such as moving from a resource specialist program to a full inclusion setting, or from a special day class to general education with supports, may require a focused assessment. The team needs current data to justify that the new placement can meet the student's needs in the least restrictive environment (LRE). A targeted assessment, such as a functional behavior assessment or a social emotional rating scale, can provide that justification.

Parent or teacher request. Any team member, including the parent, can request a new evaluation at the annual review. The district must either consent by sending an assessment plan within 15 calendar days or issue a prior written notice (PWN) explaining why the request is denied. Refusing a parent request for assessment without proper documentation can lead to due process. The team should weigh the request carefully and document the rationale.

What Assessments Are Typically Included

For most annual reviews, the team relies on existing data: report cards, progress on IEP goals, teacher observations, and the most recent triennial report. When a new assessment is warranted, it does not need to be as comprehensive as an initial or triennial evaluation. Instead, it should be targeted to the specific areas of concern.

Commonly used targeted assessments for annual reviews include:

  • Brief academic achievement measures such as the Wechsler Individual Achievement Test, Fourth Edition (WIAT-IV) or the Woodcock Johnson Tests of Achievement, Fourth Edition (WJ IV ACH).
  • Behavior rating scales like the Behavior Assessment System for Children, Third Edition (BASC-3) or the Achenbach System of Empirically Based Assessment (ASEBA).
  • Executive function measures such as the Behavior Rating Inventory of Executive Function, Second Edition (BRIEF-2).
  • Social emotional screening tools or adaptive behavior scales like the Vineland Adaptive Behavior Scales, Third Edition.

The assessment plan must be developed within 15 calendar days of the request (Ed Code 56321). The plan must describe the areas to be assessed, the instruments to be used, and the credentials of the assessor. Once the parent signs the plan, the district has 60 days to complete the assessment and hold the IEP meeting (Ed Code 56344). However, the annual review can be rescheduled to accommodate the new assessment timeline. The team should note this in the meeting minutes and issue a PWN if the original review date cannot be met.

Documentation and Timeline Best Practices

Documentation is critical at every step. The IEP team's decision regarding assessment needs should be recorded in the meeting notes, including the rationale for not assessing if that is the conclusion. If a team member disagrees, note the dissenting opinion and the basis.

If an assessment is needed, the district must issue a PWN within 15 days of the meeting. The PWN should explain the evaluation decision, the areas to be assessed, and the anticipated timeline. The assessment plan itself must be sent to the parent within the same 15-day window. The plan must be signed before testing begins.

The assessment must be completed within 60 calendar days of receiving the signed plan (Ed Code 56344). If the annual review was scheduled before the assessment is finished, the team can hold a brief status meeting to document the delay and reschedule the review for a date after the report is ready. The team should send an updated meeting notice with the new date.

When the existing triennial report is less than three years old and still valid, update only the sections that show change. For example, update the present levels section with recent classroom data and progress toward goals, but do not repeat the full cognitive battery. This approach saves time and avoids unnecessary testing.

Frequently Asked Questions

Do I need a new assessment for every annual IEP review in California? No. The annual review does not automatically require a new assessment. The team must determine whether existing data are sufficient to make decisions about eligibility, goals, and placement. If the last triennial is less than three years old and current data are available, no new assessment is needed.

What assessments are most common for annual reviews? When an assessment is needed, the team typically uses targeted instruments such as the WIAT-IV for academic achievement, the BASC-3 for behavior, or the BRIEF-2 for executive function. The choice depends on the area of concern identified in the meeting.

How long do we have to complete an assessment if ordered during an annual review? Once the parent signs the assessment plan, the district has 60 calendar days to complete the assessment and hold the IEP meeting, per Ed Code 56344. The annual review date can be rescheduled to accommodate this timeline.

Can a parent request a new evaluation at the annual review meeting? Yes. Any team member, including the parent, can request a new evaluation. The district must either consent by sending an assessment plan within 15 days or issue a prior written notice explaining the denial with a rationale.

What happens if we don't have enough current data for the annual review? If the data are insufficient, the team cannot make informed decisions about eligibility, goals, or placement. The team should document the data gap and initiate an assessment plan. The annual review can be postponed until the assessment is complete.
