Comparisons were made of three Angoff Design V
equating methods and the Tucker and Levine Equally
Reliable methods with respect to common item linear
equating with non-equivalent populations. Forms of a
professional certification test were equated with these
five methods using (1) single-link equating of selected
pairs of forms and (2) cyclical equating of selected
forms to themselves, by means of equating chains. In
the single-link equatings, raw score equivalents given
by the Design V methods tended to fall between those
obtained by use of the Tucker and Levine methods.
The chain equatings produced similar estimated bias
and estimated root mean squared error of
for the five different methods.
