Criterion-referenced testing is usually applied to the assessment of achievement. In this article, we suggest how it can also be applied to the assessment of adaptive intelligence, that is, intelligence as adaptation to the environment. In the era of the Anthropocene, we argue that adaptive intelligence is what is most important not only for individual success, but also for success in terms of preservation of the world as we know it. We define criterion-referenced testing and compare it to norm-referenced testing. We then discuss two kinds of scoring of criterion-referenced testing, namely, with respect to external criteria and with respect to internal (theory-based) criteria. We then discuss past research on intelligence that could be viewed as criterion-referenced. Finally, we suggest how criterion-referencing could be applied to the assessment of adaptive intelligence.
