Goal Attainment Scales

Goal Attainment Scaling (GAS) is a method that can be used as a means of measuring outcome data from different contexts set out on a 5 point scale of -2 to +2.

It enables the data to be placed on a quantitative measurement scale thus tackling the problem of how to adequately identify and measure qualitative goal impact and attainment. This is very useful as it enables a linking of measures from the frontline to upper levels of an organization’s management.

Examples

Table with columns showing level of expected outcome connected to a 5-point rating, and behavioural statement of expected outcomes for each relevant goal

This example is taken from Sharp (2006, p7).
