Peer reviewedWilcox, Rand R.; Harris, Chester W. – Journal of Educational Measurement, 1977
Emrick's proposed method for determining a mastery level cut-off score is questioned. Emrick's method is shown to be useful only in limited situations. (JKS)

Livingston's work is a careful analysis of what occurs when one pools two populations with different means, but similar variances and reliability coefficients. However, his work fails to advance reliability theory for the special case of criterion-referenced testing. See ED 042 802 for Livingston's paper. (MS)

An alternative interpretation of Livingston's reliability coefficient (see TM 500 487) is based on the notion of the relation of the size of the reliability coefficient to the range of talent. (Author/CK)
