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-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.

Choose settings and generate a problem.

Method performance

Error patterns

Recent Work

Review exactly what the student did, where the error occurred, and what to reteach.

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 Report

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.
