Training Evaluation Validity and Reliability

Validity = measuring what you intend to measure.

Types of Validity:

1. Content Validity: the extent to which the instrument represents the training program’s content.
   1. Low Content Validity: the instrument doesn’t represent a true summation of the program content
   2. High Content Validity: the instrument represents a good balance of all the program content
2. Construct Validity: the degree to which an instrument represents the construct it is supposed to measure
   1. The abstract variable, such as skill or ability, is the construct
   2. Can be defended through expert opinion, correlations, logical deductions, and criterion group studies
3. Concurrent Validity: the extent to which an instrument agrees with the results of other instruments
4. Criterion Validity: the extent to which the assessment can predict or agree with external constructs.
5. Predictive Validity: the extent to which an instrument can predict future behaviors or results.
