Theories
"A good theory is one that holds together long enough to get you to a better theory".1
The theoretical foundations that underlie a discipline are
far from stagnant. They are in continual motion, advancing on
a path that may intersect with many disciplines at different
times, changing direction and pace as new ideas take root. The
same is true for the discipline of needs assessment.
Needs assessment theory is both derived from and informed by
numerous other fields of inquiry – including psychology,
management, motivation, human resources, capacity development,
and others.
A group of needs assessment researchers (see Research page) are currently
working on conceptualizing a theory of needs assessment. If
you would like to join that effort, please contact us.
Below is a general list of primary theories that contribute to the study or application of needs assessment. If there are others that you would like to have us consider adding, please let us know.
