Assistant Head Reduced/Compressed Hours Calculator

Looking at a 4-day week, 9-day fortnight, term-time only or annualised hours? This calculator shows how your pay would look for an Assistant Head under different reduced or compressed patterns compared to full-time. Compare FTE and annual pay so you can weigh up options.

Assumptions and pay data

Pay data: School Teachers' Pay (England). Main (M1–M6) and Upper (U1–U3) are statutory rest-of-England points from STPCD 2025/26. Leading Practitioner uses published min–max; spine points are evenly spaced within that range (schools may set different points inside the range). Leadership uses statutory L1 minimum and L43 maximum; intermediate points are linearly interpolated for the calculator (actual L2–L42 are in STPCD). Allowances: London uplifts auto-switch by band (M1 / U1 / L1 / LP min vs zonal STPCD 2025/26); TLR and SEN as statutory ranges (see _meta.allowancesFootnote). Support: NJC SCP 5–12; STPCD zonal uplifts do not apply. Schools may use other SCP ranges.

Figures are illustrative. We pro-rate full-time band pay by FTE (e.g. 0.8 for 4-day week, 0.9 for 9-day fortnight). Term-time and annualised hours use the same dataset; employer rules may differ.
All amounts are gross. Tax, NI and pension are not deducted.
