Term datesChelmer Valley High School

Secondary • Chelmsford • CM1 7ERLocal authority: Essex

These are Chelmer Valley High School's own term dates for 2025/26 and 2026/27 — read from chelmervalleyhighschool.co.uk. The school hasn't published 2027/28 yet, so those years are filled from Essex council's calendar: term dates and holidays, but not the school's own training days, usually five a year. Expect a few extra closed days. We re-check every few days and swap in the school's dates the moment they appear.

How we read these
  1. 1Opened the term-dates page on chelmervalleyhighschool.co.uk.
  2. 2Downloaded 3 documents: Term-Dates-2026-27-final.pdf, Term-Dates-2025-26-final-with-all-….pdf, document.
  3. 3Read the dates out of the document with our language model.
  4. 4Kept 28 dates of the school's own for 25/26, 26/27; 27/28 is Essex council's dates until the school publishes its own — and we re-check every few days, so they stay right on their own.
