Clifton College is a co-educational independent school in Clifton, Bristol, England, founded in 1862. In its early years it was notable (compared with most Public Schools of the time) for emphasising science in the curriculum, and for being less concerned with social elitism, e.g. by admitting day-boys on equal terms and providing a dedicated boarding house for Jewish boys. Having linked its General Studies classes with Badminton School since 1972, it admitted girls to the Sixth Form in 1987 and is now fully coeducational. The dedicated Jewish boarding house closed in 2005. Clifton is one of the original 26 English public schools as defined by the Public Schools Yearbook of 1889. The school takes boys and girls aged between 13 and 18. It has a nearby preparatory school, Clifton College Preparatory School (known as the 'Pre'), for children from 8 to 13 which is nearby and shares many of the same facilities; also a pre-preparatory school for younger children aged 3 to 8 called Butcombe. To distinguish it from the junior schools, Clifton College proper is sometimes referred to as the 'Upper School'. There are around 720 children in the Upper School of which about a third are girls.
