Massachusetts IEP requirements: timelines, the new form, and what 603 CMR 28.00 actually says

Massachusetts runs special education on its own vocabulary and its own clocks. The IEP team is “the Team,” capital T. Disputes go to the BSEA, not a generic due-process office. The evaluation timeline counts school working days, parents get a formal 30-day window to accept or reject the IEP — partial rejections included — and since the 2024–25 school year every district has been writing on a brand-new state IEP form, the first major revision in decades. If you moved here from a state on a 60-calendar-day clock (California), or one with referral-decision deadlines like Washington, recalibrate here first. Everything below is cited to 603 CMR 28.00 or DESE’s published IEP materials.

Every Massachusetts deadline in one table

The 45-school-working-day clock bundles everything

Most states split the process into separate clocks — X days to evaluate, then Y days from eligibility to an IEP meeting. Massachusetts bundles it. Within 45 school working days of receiving the parent’s written consent, the district must have evaluated, convened the Team, decided eligibility, and handed the parents two copies of the proposed IEP and proposed placement — or a written explanation of why the student isn’t eligible (603 CMR 28.05(1)). The assessments themselves must be done by day 30, and the assessment summaries have to be available to parents at least two days before the Team meeting, which is worth flagging to families who want to walk in prepared.

Because the clock counts school working days, it pauses over the summer — but the regulation closes the obvious loophole. If consent arrives 30 to 45 school working days before the last day of school, the district must still deliver the proposed IEP or the not-eligible finding within 14 days after the year ends. A June referral doesn’t quietly become an October IEP. The front end is quick too: once a referral for evaluation comes in — and anyone can refer — the district has 5 school days to send the parent written notice and the consent package (603 CMR 28.04(1)(a)).

Parents formally accept or reject the IEP — including in part

This is the piece that most surprises case managers arriving from other states. A proposed IEP in Massachusetts isn’t implemented on silence. The parent has up to 30 days to respond, and the response can be an acceptance, a full rejection, or a rejection of specific parts (603 CMR 28.05(7)(a)). A rejection isn’t a dead letter either: within 5 days of receiving it, the district must forward the rejected IEP, placement, or eligibility finding to the Bureau of Special Education Appeals, which contacts both sides about mediation and hearing rights (603 CMR 28.08). The BSEA then owes a decision within 45 days of a hearing request. For your documentation, that means the signature page is a live compliance artifact — track what was accepted, what was rejected, and implement the accepted portions while the dispute runs. Your meeting notes and prior written notice are what the BSEA will read.

The new IEP form: what changed in 2024–25

DESE’s IEP Improvement Project replaced the state form districts had used for decades. The current IEP form carries a revision date of 11/18/2024, alongside refreshed amendment forms, evaluation and placement consent forms, meeting invitations, and the Notice of Proposed School District Action. The redesign is more than cosmetic: the student’s vision statement moves to the front and is meant to drive the whole document, and transition planning is integrated into the IEP itself rather than living on a separate planning form. DESE publishes quick reference guides — including one for parents and one on transition planning with the new IEP — plus technical guides for districts. If your district’s internal templates still mirror the old form’s section order, expect your compliance checklist to need reordering, not just relabeling.

Transition planning starts at 14, not 16

The federal floor says transition services begin no later than the first IEP in effect when the student turns 16 (34 CFR §300.320(b)). Massachusetts formalizes planning earlier: DESE’s transition guidance for the new IEP has planning become formalized as the student approaches age 14, or sooner if the Team decides it’s appropriate, with postsecondary vision statements shaping the entire IEP from that point. For a middle-school case manager, that means the 8th-grade annual review is a transition meeting — age-appropriate transition assessment, postsecondary goals, and a course of study — not something to defer to high school. At 17, add the age-of-majority notice: at 18, decision-making transfers to the student, and the district must obtain the student’s consent to continue services (603 CMR 28.07(5)) unless a court has granted guardianship.

What this means for your caseload

• Log the consent date, not the referral date, as day zero for the 30/45 clocks — but remember the 5-school-day notice duty starts at the referral.
• Get assessment summaries to families two days before the Team meeting. It’s a regulation, not a courtesy — and it changes the tone of the meeting.
• Treat the parent response page as a tracked deliverable: accepted, rejected, rejected-in-part, and the date. Partial rejections still obligate you to implement the accepted parts.
• Audit May and June consents against the 14-days-after-year-end rule before you leave for the summer.
• For transfers into Massachusetts mid-year, comparable services apply while the Team adopts or rewrites the IEP — the same IDEA rule covered in our transfer-student guide, but the rewrite lands on the new state form.
• Keep an IEP at a glance in every gen-ed teacher’s hands — Team-meeting season in Massachusetts moves fast once the 45-day clocks stack up.
