Methodology and Limitations
ElevenReady normalises source files into consistent school and year records, then presents the published figures without estimating missing results.
Progress 8 is unavailable for 2024–25 because the Department for Education cannot calculate it without the relevant KS2 baseline following Covid-era assessment disruption.
Historical allocation distances describe previous offer rounds. They do not create a fixed catchment boundary or guarantee a future place. Always confirm current admissions rules with the school and Buckinghamshire Council.
