Typical case sampling

Typical case sampling allows the evaluator to develop a profile of what is agreed as average, or normal.

These profiles can serve as illustrations for those unfamiliar with the program.

Typical case sampling can be useful on large, complex programs. They can assist outsiders to gain a rapid understanding by providing in-depth profiles of how the program typically affects people’s lives.

Program staff and informants can assist in selecting typical cases. In developing a typical case sample, the evaluator can liaise closely with program staff and key informants to develop criteria of what is typical.


On a health program, an evaluator may choose to develop a typical case profile of the background and training of health practitioners as well as patients. These profiles may be useful in determining the efficacy of the care provided by practitioners to clients.
