Massachusetts is an approval state — your district approves an education plan up front and then sets how your child's progress is assessed, so keep everything that supports both:
What to keep
Your written education plan / proposal submitted for approval (subjects, materials, and schedule)
The written approval from your superintendent or school committee (keep a copy each year)
Samples of your child's work across the required subjects (worksheets, writing, projects, photos of hands-on work)
A record of instructional time showing instruction is substantially equivalent to public school
The annual assessment your district requires (periodic testing, a progress report, or dated work samples)
Your Massachusetts filing timeline
Before the school year startsSubmit your education plan and obtain written approval from your local superintendent or school committee.
All year longKeep work samples and your instructional-time record current as you go.
End of the yearComplete the assessment method your district set — a test, a portfolio review, or dated work samples — and provide the progress report requested.
Each new school yearRenew your approval before instruction begins.
