Survey
and Evaluation of Recently Developed Procedures for Setting
Standards on Educational Tests
November 2000
The Article
Standards are an increasingly important issue in K-12 education. But
how do educators establish standards? What methodologies can
educators use to establish workable and effective educational
standards? MSU Professor Mark Reckase presents a general framework
for describing components of standard-setting procedures, develops
some criteria for considering alternative standard setting methods,
and describes a number of potential methods.
Discussion
Although it may seem simple, standard setting is actually a very
complex process that involves a number of components, each of which
is important. Reckase describes five components in standard-setting
methodology: (1) an “authority” to set policy, (2) a content
domain (mathematics, English, etc.) that is the focus of the
standard, (3) a selection of persons (judges) to make judgments
about desired levels of performance, (4) methodology for collecting
judgments and estimating standards, and (5) some means for reporting
the results of the process. Each component is critical to the
process. For instance, without sound methodology for collecting
information from judges about their recommendations for standards,
the connection between policy, content, and scores cannot be
defended. Because of the importance of this component, many
alternative standard-setting methods have been developed and
substantial work is being done to evaluate the quality of
alternative methods. Reckase describes a number of methods such as
the bookmark method, the anchor-based procedure, generalized
examinee-centered method, and the multistage aggregation method. The
various methods provide differing methodologies from asking judges
to rate increasing amounts of performance information over rounds
(multi-stage aggregation method) to having judges use a 7-point
rating scale related to four performance categories of minimal,
partially, proficient, and advanced (generalized-examinee centered
method). All of them have potential, but most have been used only in
limited research or pilot studies. Because standard setting can be
implemented in a number of different ways, it is difficult to
identify firm criteria for determining whether a standard-setting
procedure will likely give sound results.
A very good standard-setting method can give poor results,
for example, if the judges are not properly training, or if they do
not have the necessary content background. Reckase provides readers
with four criteria for a sound standard-setting methodology: (1)
minimal level of distortion in converting judgments to a standard,
(2) moderate to low cognitive complexity of the tasks judges are
asked to perform, (3) acceptable standard errors of estimate for the
scores, and (4) replicable process for conducting the standard
setting study.
What It Means
To You
Standards are increasingly important tool for accountability and are
the subject of much attention by lawmakers, parents, administrators
and teachers. But as Reckase’s article points out, setting
standards is a lengthy and complex process that involves a number of
crucial components in order for results to be a valid reflection of
performance.
