Gardner J & Leitch R (1998) Evaluation of the Northern Ireland Summer Literacy and Numeracy Schemes Pilot: Summer 1998. Department of Education - Northern Ireland. http://gtcni.openrepository.com/gtcni/bitstream/2428/8346/1/Summer%20literacy%26numeracy%20scheme%20evaluation%201998.pdf
First paragraph: The evaluation covered 29 of the 31 schemes operating in the summer of 1998, under the aegis of the four education and library boards: BELB, SELB, SEELB and WELB. No schemes were operating in the NEELB area. One scheme was not visited owing to its dates of operation being communicated incorrectly to the evaluation team and the other was missed because of logistical reasons. Of the original 39 schemes notified to the evaluation team, six were cancelled before they could start. In the remaining two cases, it was not possible to establish contact. The report below is based on the 29 visited schemes.
