APPENDIX 1 WEIGHTING SPECIFICATION
1. In order to ensure results were representative of ILA100 and ILA200 applicants, data was weighted using the learndirect database from which the sample was drawn. For increased accuracy at the weighting stage we used inter-locking sex-age weights. The same weighting targets were used at wave 1 and wave 2. Data was weighted to the following specifications:
