Attention is focused on the estimation of the KR20 reliability coefficient when data are incomplete. In terms of point estimate, it is found that the analysis of variance procedure (Henderson's Method 1) would be most suitable among the three techniques studied. Confidence coefficients are provided for the KR20 when data are incomplete.
