The Early Intervention Foundation (EIF) has published a guide addressing six of the most common issues with evaluation, design and execution that undermine confidence in a study’s results. Based on more than 100 in-depth assessments of the evidence for the effectiveness of programmes designed to improve outcomes for children issues identified include: no robust comparison group; high drop-out rate; excluding participants from the analysis; using inappropriate measures; small sample size; and lack of long-term follow-up. The guide includes advice on planning and delivering evaluations on how these issues can be avoided or rectified.
