Our client, Test Innovators, provides practice curriculums for the Independent School Entrance Exam (ISEE) in an effort to address the gap in resources for adequate preparation. The biggest issue holding them back from success was a process that analyzed the standardized grading system which would give them insightful information to use and relay to their users. We tackled this problem by performing data cleansing, modeling, and analysis on data sets provided by the client which was collected from students who had already taken their practice exams. To gauge success and effectiveness, our user’s scores will be 10% higher than non-Test Innovator users and our system will also provide grade predictability within one grade level since the stanine grading scale ranges from level one to level nine. With this ISEE grading analysis process, we provide high levels of confidence and preparation for our client’s users in their test-taking careers.
