Maximizing professional credentialing examinations involves balancing several factors, including assessing the optimal examination length and determining an adequate number of options. This session will be broken down into two parts. The first part will review methods to determine the optimal number of items required by highlighting support for reducing the number of items. Data from a certification exam will be used to illustrate these findings.  The second part will include a review of the literature on the advantages and disadvantages of reducing the number of item options and will present empirical findings suggesting that 3-option items may be sufficient and advantageous.
