Do prep schools like Loomis, Deerfield, Exeter Do Math Placement Tests in 9th grade?

Andover has a slightly lower math for kids who might need to catch up a bit,

To be clear on concept, Andover’s “lower math” is more advanced than the typical regular 9th grade math at the LPS; It covers Algebra I and Geometry in a single year. And it is the class most 9th graders take.
