The document summarizes a presentation on evaluating the effectiveness of the Letterbox Club in improving educational outcomes for children aged 7-11 in foster care in Northern Ireland. It found that children who received Letterbox Club packs showed improvements in reading accuracy, reading comprehension, and number skills based on pre and post testing. However, a controlled trial is still needed to conclusively determine how much of the improvement is directly due to the Letterbox Club intervention. Recommendations include expanding the number games in packs, conducting a rigorous controlled trial, and considering additional outcomes like enjoyment and confidence.
