The data included here are abbreviated norms, presenting only percentile rank as a function of raw score and overall test statistics. Complete norms are computed, printed, and subsequently shipped with orders for examinations as soon as sufficient data is received at the Examinations Institute. If you have purchased copies of an examination for which you have not received norms, please contact the Examinations Institute at acsexams@examsinstitute.org.

If a newer exam is not listed here, it either has only recently been normed, or lacks sufficient data return to calculate a norm. You can obtain feedback on how your students are doing for such exams in the “Score Reporting” section, where you can enter your scores and have them instantly compared with student performances we have received thus far. For older examinations that are not included in the list, please contact the Examinations Institute.

New tool for norm reduction – customize your exam for your needs

In response to requests from many of you to be able to generate norms for a reduced set of items for your ACS exam, we have developed a tool for this.  Available for general and organic chemistry and biochemistry exams, you can select your test, select which items to remove and observe the change to the norms.  You also can upload your data for a downloadable file with your students’ adjusted norms and course information.  This site can be accessed here.
