Middlesex School of Concord, Massachusetts sponsors Middlesex School Savings Plan, a 403(b) plan. Its Form 5500 for the plan year ending 31 Aug 2025 shows 350 participants (227 active) and $27.1M in net assets.
Net assets came to $77,323 per participant, well above the $48,746 median for defined contribution plans with 250 to 499 participants and above the $73,018 median for defined contribution plans in educational services. The figure is an average across everyone in the plan, including former employees with small balances; Form 5500 holds no individual account data.
Schedule C lists 1 service provider organisation paid $5,000 or more, with reported compensation of $36K: $102 per participant, well below the same-size median of $141. Administrative expenses charged to the plan were $36K. Schedule C does not capture every cost: fees netted from fund returns and fees the employer pays directly are outside it.
Across the filings on record, net assets went from $5.8M in 2009 to $27.1M in 2024 (up 367%), and participants from 168 to 350 (up 108%).
The independent accountant's opinion on the financial statements was disclaimer, from an audit whose scope was limited under ERISA section 103(a)(3)(C) to exclude investment information certified by a bank or insurer.

Questions and answers
How big is Middlesex School Savings Plan?
350 participants at the end of the plan year ending 31 Aug 2025, of whom 227 were active employees, with net assets of $27,062,900. Among defined contribution plans that places it in the 250 to 499 participants band, which held 17,456 plans in plan year 2024.
What does Middlesex School contribute per participant?
This filing has no Schedule H financial statement, so employer contributions are not reported here.
What fees does the plan pay and how do they compare?
Schedule C reports $35,573 in compensation to service provider organisations, $102 per participant or 0.13% of net assets. The same-size median among plans reporting any Schedule C compensation was $141 per participant. Administrative expenses on Schedule H were $35,573. Investment costs deducted inside mutual funds and other pooled vehicles are not itemised on Form 5500, so these figures are a floor rather than a full cost.
Who runs the plan?
The sponsor is Middlesex School. Recordkeeping or administration: Fidelity Investments. The financial statements were audited by RSM US LLP. Form 5500 also names the plan administrator's signer and other individuals; this site publishes organisations only.
Was the audit opinion unqualified?
The filing reports an disclaimer opinion from a limited-scope audit, in which the accountant did not audit investment information certified by a bank or insurance company. A disclaimer of opinion was the usual result of a limited-scope audit under the rules in force before 2021 and is not by itself a finding about the plan.
How current is this, and does it show my balance?
This is the Form 5500 for the plan year 1 Sep 2024 to 31 Aug 2025, received by the Department of Labor on 11 Jun 2026. Filings are due seven months after the plan year ends, or nine and a half with an extension, so the public record always runs a year or more behind. It contains plan-level totals only: no individual balances, contributions or names of participants exist in the data.
