This 1.5 hour webinar will cover some of the important technical details that assessors should be familiar with when conducting vocational evaluations.  Various measurement scales will be reviewed and the importance of understanding what mathematical operations can be applied to numerical data will be discussed.  We will review the types of tests that are used for vocational assessments as well as the principles of testing.  Specific information about the norms for some of the most popular assessments used in the field of vocational evaluation (i.e. WRAT-4, TONI-4, WPT, CWPI, GATB, etc.) will be reviewed.  The various types of commonly reported scores will be explained, with attention given to how test scores relate to vocational potential.  Finally, we will discuss the importance of understanding the standard error of measurement and standard error of difference for given tests and how they impact the interpretation of test results.  As much as possible this session will provide assessors with direct references to where all of this technical data can be found in the examiner manuals for the tests discussed.
