Preparing children for life's horizons



Chemistry, Biology and Physics are taught as distinct subjects

Small Classes...
...Big Difference

We are a co-educational school for pupils aged 3 - 13yrs.  Pupils can join us at any stage. Many join us for their 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 both inside and outside the classroom - see "The Thornlow Timesor visit "Latest News" to read more!

Thornlow pupils study Spanish, French and EnglishAll languages are timetabled on the curriculum and are taught by specialist language teachers.  To enhance learning, our incredibly strong links with Spain provide exchange opportunities.  Our traditionally English classic school uniform, exudes quality, just like our language department!

We're a small school, but we have a giant reputation for sailing. We hone our skills in the safe waters of Portland Harbour.  During winter months we have also embarked on an Outdoor Activities Programme which included rock-climbing and mountain biking.

Children in our Early Years Nursery even learn French!
