About Wareham School District

Families in zip code 02558 (Onset, Massachusetts) are assigned to Wareham School District for public education through 12th. This overview covers the district’s funding levels, scale, rating, and what to expect from the enrollment process if you’re moving to or within this zip code.

Understanding the 3/10 Rating

With a rating of 3/10 (below average), Wareham School District ranks among Massachusetts’s below average-rated school systems. Our ratings are based on state assessment results — the share of students scoring proficient or above in reading and math, as reported in Massachusetts’ MCAS grades 3–8 assessments (2024–25 school year). We average each district’s reading and math proficiency, then rank it against other districts in the same state to produce a 1–10 score. Because Massachusetts is compared only against itself, the rating reflects how this district performs relative to its in-state peers.

Wareham School District carries a below-average rating, with reading and math proficiency rates below typical Massachusetts benchmarks on state assessments. A below-average score reflects test performance relative to other districts — not necessarily teaching quality or school culture, and some of these districts have schools with strong communities and dedicated staff. Families should research specific school quality, visit in person, and ask about available programs. Also ask about open enrollment and magnet options that may offer alternatives to the default attendance-zone assignment.

Enrollment for Families in Zip Code 02558

Two homes on opposite ends of the same zip code may be assigned to different schools within the same district.

To confirm your specific school assignments, contact Wareham School District at (508)291-3500 or visit warehamps.schoolblocks.com. Typical enrollment documents include proof of address, a government-issued birth certificate, immunization records, and any existing school records or IEP documentation. If your child has an IEP or 504 plan, bring that documentation to enrollment — Massachusetts districts are required to continue services within a reasonable period. Fall enrollment windows typically open in late winter or early spring; contact the district for exact dates and required steps.
