We are a co-educational school for pupils aged 3 - 13yrs.  Pupils can join us at any stage a few just for Years 7 & 8.  Our pupils go on to secure scholarships at prestigious public secondary schools, or their state equivalents such as The Thomas Hardye School.  "ItsLearning" allows parents to stay in touch with their children's lessons on a daily basis.

Stage Not Age

We take an unashamedly traditional approach to the vital importance of the basics; mental arithmetic, times tables, good grammar, spelling and punctuation.  We ensure we tailor learning to the specific needs of the pupil.  We strive to balance excellence with inclusion - see "Thornlow Times 13-14", "Autumn Term 2014or visit "Latest News" to read more!
