The Department of Education collects data annually on the highest qualification and destination of Northern Ireland grammar and secondary school leavers. In addition to the qualifications and destination data, such items as year group, sex, ethnicity, religion, free school meal entitlement, special educational needs and the pupils home postcode are also collected. Other items such as the school management type are also included in the dataset.
Statistical releases issued by the Department, in relation to qualifications and destinations of school leavers, can be accessed here.
Additional information on the processes and procedures involved in the collation of school leavers' data is also available.
