Internal versus External Evaluation
There are many considerations to take into account when deciding whether to conduct an in-house evaluation or to seek out outside help. If an evaluation requires independence and objectivity or is highly technical, or if staff time and resources are limited, an external evaluator might be the better choice. Alternatively, if a program has little money to spend on evaluation and has internal expertise, an internal evaluation might be preferable. Hybrid models (internal and external team members) can combine the best of both worlds. Read more on deciding between hiring an internal or external evaluation.
