Binary, probability, and ordinal scoring procedures
for multiple-choice items were examined. In a
situation where true scores were experimentally
controlled by the manipulation of partial information,
it was found that both the probability and ordinal
scoring systems were more reliable than the
binary scoring method. A second experiment using
vocabulary items and standard reliability estimation
procedures also showed higher reliability for the
two partial information scoring methods relative to
