This is a list of some of the endowed schools in England and Wales existing in the early part of the 19th century. It is based on the antiquarian Nicholas Carlisle's survey of "Endowed Grammar Schools" published in 1818 with descriptions of 475 schools but the comments are referenced also to the work of the Endowed Schools Commission half a century later. Most English and Welsh endowed schools were at the time described as grammar schools, but by the 18th century there were three groups: older prestigious schools becoming known as "public schools"; schools in manufacturing towns that innovated to some extent in syllabus; and more traditional grammar schools in market towns and rural areas.
A medieval grammar school was one which taught Latin, and this remained an important subject in all the schools, which generally followed the traditions of the universities of Oxford and Cambridge, from which almost all of their graduate schoolmasters came. Some of the schools listed by Carlisle had long been fee-paying public schools, although in most cases (as at Eton and Winchester) retaining some provision for the teaching of "scholars" who paid reduced or no fees.
An endowment for educational purpose was intended by the founder or founders to be legally binding in perpetuity. However the object of such endowments was not always fully honoured by those controlling the schools.
Carlisle compiled his list by means of a questionnaire, which was not always answered. The Commission's report built on his research, while not accepting all his claims on the continuity of certain schools from monastic and chantry foundations, which affected the dating of schools. The chronological list in the report has numerous further details of endowments.
There is little consistency in the actual names of grammar schools from this period. Many were called "free schools". Carlisle used some unorthodox spellings, and he listed Hampshire under its alternative historical name of Southamptonshire.
For Eton College see Buckinghamshire.
For Hampshire see County of Southampton.
Carlisle referred to Hampshire as Southampton.
Monmouthshire is listed separately.
