Math Placement Tests

Seattle Central uses the ALEKS PPL Test to evaluate math proficiency, a flexible way to determine student eligibility for math placement. While the college is operating with limited services during COVID-19, the ALEKS PPL math placement test may be taken online.  Students are allowed to re-take the test only one time, and there is a mandatory 48-hour waiting period before re-taking the test.  This online testing allowance is considered a temporary arrangement, and the Math Department will review the decision when the college returns to normal operations.  Please see below for step-by-step instructions for taking ALEKS PPL online.
