Reliability generalization (RG) is a measurement meta-analytic method used to explore the variability in score reliability estimates and to characterize the possible sources of this variance. This article briefly summarizes some RG considerations. Included is a description of how reliability confidence intervals might be portrayed graphically. The article includes tabulations across various RG studies, including how frequently authors (a) report score reliabilities for their own data, (b) conduct reliability induction, or (c) do not even mention reliability.
