Even in this case, this external synthesis method is still called meta-analysis. A meta-evaluation of multiple evaluations would involve looking at how good the evaluations are. If the studies are invalid, then so will the results of the meta-analysis be. Meta-analysis has been abused, because people haven't looked carefully enough at how good the studies were before deciding the combine them. In other words, the intradisciplinary evaluation hasn't been done competently.
Intradisciplinary evaluation is the biggest of all the evaluation subfields.
And meta-evaluation is the only way we can upgrade the quality in the field of evaluation. Internal Synthesis Internal synthesis is pulling together performance on a number of dimensions of merit to draw an overall evaluative conclusion. The trick is that you have to weight more important dimensions higher than other dimensions. In many cases, the issue is not just the logic of the synthesis, it's the practice. Take, for example, proposal evaluation .
