Currently looking around the Herts/bucks area for a prep school for DS. Have seen mainly positive feedback about lockers Park online but its ISI inspection report in 2017 seemed to be concerning especially on the teaching/academic side? Whilst most schools in the area eg the Beacon get excellent in many aspects, for lockers Park it was ‘good’ across the board. How much should one read into this? To which extent do they stretch the more able boys? Are the class sizes (10-12) too small? Any current or recent experience would be really helpful xx
