For those of who work in Enrollment Management and routinely analyze higher ed data, I wanted to share an easy way to convert ACT to equivalent SAT M+V scores in R. I am dynamically building a dataset that uses the concordance chart located here. Simply, use this data frame and merge it onto your existing data (?merge) to calculate the “best standardized test score” for a given recruit, applicant, etc.

If you aren’t using R, give it a shot, it’s worth the effort and undoubtedly you will begin to find SAS and SPSS are too much work.

Let’s save the debate on the validity of standardized tests for another day…….
