H-1B sponsorship profile: Middlesex School. Across U.S. Department of Labor LCA disclosures, Middlesex School filed 5 Labor Condition Applications covering 5 H-1B worker positions between fiscal year 2023 and fiscal year 2025. The employer’s DOL certification rate sits at 100% (5 certified of 5 filed), a useful proxy for how cleanly their prevailing-wage attestations pass the Labor Department’s preliminary review before USCIS adjudication.

Compensation spread. Offered wages on Middlesex School’s H-1B petitions range from $58,120 at the low end to $75,850 at the high end, with a petition-weighted average of $63,818. That range reflects the mix of occupations the company sponsors, led by MUSIC TEACHER (3 petitions at $60,000 avg), followed by Associate Dean of Diversity, Equity and Inclusion. H-1B salaries reported on LCAs must meet or exceed the DOL prevailing wage for the role and worksite, so the spread also tracks wage-level geography and seniority.
