Gardner J & Leitch R (1999) Evaluation of the Northern Ireland Summer Literacy and Numeracy Schemes: Summer 1999. Department of Education - Northern Ireland. http://gtcni.openrepository.com/gtcni/bitstream/2428/8347/1/Summer%20literacy%26numeracy%20scheme%20evaluation%201999.pdf
The evaluation covered all of the 61 (1998: 31) schemes scheduled to operate in the summer of 1999, under the aegis of the education and library boards. Six schemes which ran in 1998 but not in 1999 were also contacted to seek their reasons for not providing a scheme in 1999. Of the 61 schemes in 1999, 31 were visited for observation and interview purposes at least once (1998: 29), 13 were visited twice and six were visited three times. Telephone interviews were conducted with the scheme leaders in a further 20 schemes, with five of these being followed up by second interviews later in their period of operation. Telephone inquiries on enrolment numbers were made with the remaining ten schemes. The report below is based on the sample of 51 schemes, which were visited or for which interviews were conducted by telephone, except where it is specifically noted that the findings relate only to the 31 schemes visited.
