What Are the Potential Uses of Concordance Tables?
A variety of stakeholders use concordance tables to compare scores across the ACT and the SAT to inform
policies, processes, and decisions. College counselors, students, and their families use concordance tables to
inform college searches and explorations. Policymakers, researchers, and K–12 educators use concordance
tables to aggregate scores across tests to measure college readiness for groups of students. Colleges,
universities, scholarship organizations, and athletic conferences also use concordances in a variety of ways,
including determining eligibility for a program or scholarship.
§ Comparing SAT and ACT scores across different students. When scores from either test are accepted,
concordance tables can help institutions or other stakeholders who need to compare scores.
§ Establishing a policy using comparable scores from both tests. An institution, scholarship, or
program may use a specific test score as one factor to establish eligibility.
§ Converting scores for use in a predictive model or index. Many colleges and universities have
built indices or models to predict the likelihood that individual students will apply, enroll, or succeed
academically. These models typically include a variety of factors, including test scores, high school GPA,
and course rigor. Institutions can apply the concordance tables in these prediction models.
What Are the Key Considerations and Limitations When Using the
Concordance Tables?
Using SAT and ACT scores in a consistent, psychometrically appropriate way as one component of a holistic
admission process will help ensure all students are treated fairly in the admission process. While the
concordance tables can be used for a variety of purposes, higher education professionals should keep the
following considerations and limitations in mind:
§ The ACT and the SAT are different tests. The ACT and the SAT measure similar, but not identical,
content and skills. A concorded score is not a perfect prediction of how a student would perform on the
other test. Concorded scores should be interpreted as the scores with the same rank within a group of
students who take the tests at approximately the same time.
§ Concordances are used to compare individual scores, not aggregate scores. Users should avoid
converting aggregate scores (e.g., mean, median, ranges) using concordance tables, as this could
introduce additional sources of error.
§ Users should avoid making decisions based solely on a concorded score. Admission and enrollment
professionals should use multiple reliable and valid measures when making decisions to account for the
many factors that impact academic performance in college.
§ Note the prediction error (more details below). Users should consider this when using the
concordance tables to predict how a student would have performed on the ACT or the SAT.
§ Concordances are sample-dependent. While concordance results can vary by sample, the ACT/SAT
concordance sample was statistically weighted to more closely reflect the demographics, school attributes,
and high school GPA of the population of students who take the ACT, SAT, or both tests.
§ Institutions should not superscore across the SAT and ACT tests. Superscoring across 2 different
tests is an imprecise way of understanding whether a student meets a certain academic threshold.
Combining scores from the ACT and the SAT in a single superscore is strongly discouraged.
