Credentialing programs were surveyed to ascertain the procedures that
they use to set performance standards on multiple-choice and open-ende
d assessments. For multiple-choice assessments, these programs mostly
employ variations on the Angoff (1971) standard-setting method. Proced
ures used with open-ended questions showed more divergence; some agenc
ies use a question by question approach, whereas others utilize method
s that consider the assessment results more holistically. Implications
of these standard-setting practices from credentialing agencies to th
e National Assessment of Educational Progress (NAEP), including the co
nsequences of the assessment on the individual candidate, the matrix s
ampling construction of NAEP-assessments, the multiple cutpoints of th
e NAEP assessment program, and the types of validity evidence that are
typically gathered to support the validity of the performance standar
d, are discussed. Generalizations of these standard-setting methods fr
om the field of professional licensure and certification should be mad
e with caution.
