Methodology and timing

  • This phase mirrors the official DfE Inclusive Mainstream Fund workbook estimate published on 2026-03-25.
  • Formula context only: GBP 3,000 lump sum, GBP 16 per primary pupil plus GBP 79 per primary low-prior-attainment pupil, and GBP 14 per secondary pupil plus GBP 88 per secondary low-prior-attainment pupil.
  • The school methodology uses October 2025 census pupil counts, 2025 to 2026 authority proforma tool low-prior-attainment proportions, and the 2026 to 2027 area cost adjustment.
  • DfE said final school-level allocations will be confirmed and published in May 2026.
  • Maintained school funding is paid to local authorities at the end of June 2026, and academy trust funding is paid directly in early July 2026.
  • The published workbook excludes Aldgate School (URN 100000), Five Islands Academy (URN 144638), Thomas Telford (URN 123627), Emmanuel College (URN 108420) because of special funding arrangements.

Guidance and use

  • This page does not rebuild the schools formula from user-entered pupil and low-prior-attainment counts. It shows the published DfE workbook estimate keyed by URN.
  • Enter the school's URN as recorded on the October 2025 school census.
  • If you do not know the URN, check Get Information About Schools before relying on the result.
