Reports by Board of Education and successors HM Inspectors on secondary institutions which made application to be recognised as efficient under various Education Acts and regulations.
The series includes reports by specialist inspectors on particular subjects, replies to a memorandum issued to inspectors in 1932 on the health of school children, and notes of conferences held between the governing body and the panel of inspectors at the time of inspection.
HM Inspectors' reports vary in frequency, scope and content in order to meet the board's particular administrative requirements. A full inspection was conducted by a panel of inspectors; occasionally an interim report resulted from a full inspection and subsequent reports are described as 'supplementary', 'follow-up' or subsidiary'.
Some files relate to Wales, the Channel Islands and the Isle of Man.
Welsh reports show the extent to which the recommendations of the 1927 Departmental Committee on Welsh in Education and Life, regarding the teaching of Welsh in the Schools, were implemented.
