How to Register
Once you’ve ensured that you meet all of the eligibility requirements, you can register for the exam!
To get started, you’ll need to submit an application on ASCP’s website. The application will ask you for your contact information and any documentation to prove your eligibility (among other things).
When you submit the application, you’ll also need to submit the $225 application fee.
Once your application is approved, you should receive an Authorization to Test (ATT), which will allow you to set up a testing appointment.
Exam Scores
The MLT test is scored using a scaled scoring method. Here’s how it works:
You will need a score of 400 to pass the test.
The reason your raw score is converted to a scaled score is because everyone who takes the test is given a slightly different set of questions. Since everyone has a different arrangement of questions, and because some questions are harder than others, converting your raw score to a scaled score ensures a more even playing field.
If you pass, you’ll get a certificate mailed to you within a couple of weeks!
Retaking the Exam
If you didn’t get a passing score on your first try, that’s okay! You can retake the test after a 90-day waiting period. Just keep in mind that you will have to pay the full testing fee every time you retake the test.
If you take the exam five times without passing, you won’t be able to take it again unless you are eligible under a different eligibility route.
