This range of courses reflected the nature of Tottenham's population and industry at the time. Industry consisted mainly of many small engineering and manufacturing firms, together with the nascent gas and telephone companies. There was also a considerable amount of building work with a rapid development of houses, shops, commercial and civic buildings taking place in the district at this time. Tottenham's population was mainly residential, with clerks and professional workers commuting to the City and other nearby areas. The 1911 Report noted the difficulties faced by evening-class students who often did not arrive home from work until 7.30 or 8.00 pm. Nevertheless, by 1911 there were 1,191 evening students. In 1913 the County School moved to its new building on Tottenham Green and the Polytechnic was able to expand by extending daytime courses. A day Junior Technical School offering a two-year course for students age 13 to 16 was opened. The junior day schools were enlarged again between the wars with a Junior Technical School for boys age 13–16 in building and allied trades and a Junior Commercial School for girls and boys age 13–16 offering a general education, together with office and clerical skills. These schools provided a secondary education that could lead to apprenticeships in industry or careers in business and the professions. There was also expansion in the third department of the Polytechnic, the Evening Institute, with four other centres across Tottenham being used. Classes were offered in art, science, matriculation, secretarial, accountancy and languages. There were courses in banking and the civil service, as well as technical and building work. The pioneering Blanche Nevile School for the Deaf, run by Tottenham Borough Council, was in nearby Philip Lane and the Polytechnic responded with classes in lip reading for teachers and parents, and language skills classes for deaf adults. Tottenham Technical College Student numbers rose from 857 in 1908–9 to 102,827 in 1938–39 and rebuilding became a necessity. Grove House was demolished in 1936 and the new building was opened in 1939. The Polytechnic was renamed Tottenham Technical College. The War disrupted work of the College, although courses continued to run, particularly as there was an urgent need for skilled labour in building and engineering. Part of the College was taken over by the Civil Defence, the control room for the Tottenham ARP (Air Raid Precautions) and the Auxiliary Fire Service, and normal work was frequently
