This research note proposes two reliability coefficients for tests with components of unknown functional lengths. The derived coefficients are extensions of the techniques devised by Kristof and Feldt and do not require a reduction of test components into parts. Simulation study indicates that the new coefficients yield reasonably stable reliability estimates when the number of test components is small.
I am grateful to Min-Te Chao for helpful comments on earlier drafts of the manuscript, and to Lien-Chi Yu for programming the simulation part of the study.
