The Department publishes data on absence from school by type of school for children who have been looked after continuously for at least twelve months at 31 March. Figures for 2013 to 2016 are in Table 5 of the Outcomes for children looked after by LAs: 31 March 2016 statistical first release, which is available at: www.gov.uk/government/statistics/outcomes-for-children-looked-after-by-las-31-march-2016. School absence figures for all children over this period is also presented in this table.
The above statistical first release provides school types; state-funded primary, state-funded secondary and special schools. A more detailed level of school type is not readily available and it is unclear if it is required.
