We have been designing a series of experiments on comparing different active reading techniques for college students. In most of the studies we found in the literature, the passages are arbitrarily chosen based on the courses that the researchers teach or the topics related to their subject pools.
Are there standardized reading comprehension tests that are reliable and generalizable for college level students? Unfortunately, we could not find any ACT, SAT, AP, or IB reading comprehension tests that are publicly released for research purposes. Passages that cover a variety of topics like humanities, social studies, natural sciences, and literary narratives and similar in length to the ACT long passages are what we are looking for.
If such standardized tests do not exist for researchers, how do you advise we generate such reliable and generalizable reading comprehension tests?
