Measurement and evaluation are critical components in a successful TDM program. Measurements can be varied, and the meaningfulness of measurements can also vary, especially according to the audience. Measurements should support the collection of performance metrics, which should in turn support evaluation. Measurement is neutral, whereas performance measures and evaluation are standards-based, and can indicate success and failure.[1]

This written guide will review the following information, and provide additional resources for expanded learning:

·       Measuring TDM Activities

·       Basic Data Computation

·       Extrapolation Metrics

·       Survey Basics

·       Statistics Basics

·       Measuring at Different Scales

[1] Performance Metrics and Evaluation are covered in a detailed way in the ACT TDM-CP Performance Measurement Module Webinar (see Additional Resources Section). The resource you are reading focuses primarily on measurement. While measurement is neutral, the resulting performance metrics and evaluation are not. Transparent recognition of success, and failure, in concluded programs is important for future program design. Recognition of successes and failures also has a role in influencing the design of ongoing programs.
