Automatic Goal Analyzer

The app reads the goal and proposes what to assess, the problem conditions, and how progress should be measured.

Enter or paste the math goal above. The analysis will update automatically.

Teacher review required: The analyzer does not rewrite the IEP or make an IEP-team decision. It proposes an app configuration from the goal text. Review the interpretation and correct anything that does not match the current IEP before applying it.
Percent accuracy used for the progress target line.

IEP Goal Measurement Plan

Choose the objective measurement stated in the IEP. This determines how the app scores the goal and what appears on the primary progress graph.

Compliance safeguard: the app records the measurement rule; it does not decide what the IEP goal or criterion should be. The measurement settings should match the current IEP as written.

Probe-Based Goal Monitoring

Use this when the IEP goal is written as a score per probe plus a consistency rule, such as 5/5 problems on 3 of 4 assessments.

IEP Goal Practice Scope

Controls what the student can practice and which Independent attempts are eligible for IEP progress monitoring.

Word-Problem Read Aloud

Controls browser text-to-speech for word problems. The app reads only the problem text, not answer choices or the correct operation.

Use the setting that matches the student's current IEP/504 plan or teacher-selected instructional support. The app records whether read aloud was used on an attempt.

IEP-required accommodations / modifications

Only select items actually contained in the student's current plan. These are stored separately from teacher-selected strategies.

Teacher-selected instructional strategies

These can change based on instruction and performance and are not represented as IEP changes.

Multiplication

Method Comparison

Compares instructional methods using unique independent attempts only. A method needs at least 3 independent attempts in an operation before the app treats the comparison as usable.

Monthly Progress Data

This page fills itself only from practice attempts marked Independent. Prompted work is excluded from progress-monitoring calculations.

Progress Narrative & Goal Draft Assistant

Teacher-only drafting support. App data are one source of information and do not independently determine IEP need, eligibility, services, or final annual goals.

Select a reporting period and generate a draft.

Possible IEP Goal Builder

DRAFT — Teacher/IEP team review required. A suggested goal should only be used when the skill deficit is connected to a disability-related need documented in the PLAAFP and considered with other current data.
Complete the PLAAFP-connected need field before generating a goal draft.
