ABSTRACT
After an item is written, several item improvement activities should be undertaken. Both research and experience have shown that many Me items are flawed in some way at the initial stage of item development, so these activities are much needed. The time invested in these activities will reap many rewards later. The more polish applied to new items, the better these items become. However, some of these activities are more important than others and deserve more attention. We can view the processes described in this chapter as part of the validation process. Documentation of these activities constitutes an important source of validity evidence (Downing & Haladyna, 1997 j Haladyna, 2002). Table 8.1 lists six standards addressing qualities of test items that come from the Standards for Educational and Psychological Testing (AERA et al., 1999).
