You'd have to miss a TON of school for anyone to even care at all.

If you need more, just call in sick. Nobody cares in spring of senior year.

The regulation says https://ww2.montgomeryschoolsmd.org/departments/policy/pdf/jea-ra%20nondiscrimination.pdf

A number of activities or work
situations that the principal/designee should excuse when approval
for the absence has been requested five school days in advance in
writing from the parent/guardian/eligible student are included
below:
(1) Visits to college campuses and participation in college
orientation programs (see local student handbook for
limitations)

https://www.montgomeryschoolsmd.org/uploadedFiles/students/rights/0848.22_2022-23_StudentRightsAndResponsibilities_WEB.pdf says the same thing.

Poolesville high school says they limit college visits to 3. Other schools may have different limits, but I think 3 days is the general expectation.

Our secretary told us 3 days per semester, not per year. But who knows. It might vary school to school.

I don't know if it's seniors only or if juniors get this benefit, as well.

It’s 3 days excused. Email your HS attendance secretary to get their process. However, I wouldn’t use those days in fall. Save them for spring when your DC is deciding between schools or their preferred school has an admitted student event you want to travel for.

OP I am pretty sure there is a form to fill out and must be provided in advance. I think three trips.

Please check with your HS or look on MCPS website.

Are they considered an excused absence? It’s not listed on my kid’s HS attendance form as a reason.
