New sections have been presented on the critical EMS problem as well as Public Education Exercises. The chapter “Best Practices in Assessment Center Exercises” provides many new examples of how candidates can achieve superior performance in many different kinds of assessment exercises. The text continues to offer invaluable insight concerning the reliability, cost-effectiveness, and objective methods for the selection of candidates for higher appointments. Included topics are the advantages of the assessment center; objections to assessment centers; typical and effective assessment exercises; center design and administration; selection and training of assessors; candidate evaluation, scoring, and feedback; preparing for an assessment center; best practices; greatest blunders; and ensuring candidate satisfaction with assessment methods.
