The new regional model for HS in MCPS (assuming it passes) is supposed to address 'less frequently taught languages' and/or have a school in each region focused on languages, but right now you'd need to a) live in the catchment area for a given MS or HS that you wanted (or get into a MS that articulated into a HS that you wanted); or b) choose or lottery into an MSMC MS (but I don't think any of them offers anything different from Spanish or French); or c) choice into or application into a DCC or NEC HS that you wanted. All of these except living in your school of choice carry some risk that it won't go your way - and HS is likely all changing in the very near future. If there's a language that really matters to DC that isn't Spanish or French, you might want to _also_ think about classes outside of school

You go to each website. Sometimes the websites are out of date, and in that case you need to email their World Language Coordinator. Most of the time, you're pretty guaranteed to have some level of French and Spanish. Some high schools have more. Walter Johnson has Latin. Walt Whitman is famous for its CIA-approved languages.

You potentially could go to the website for each school you're interested in and click on their World Language department page and see if there's a listing there.

For example on the Walter Johnson site:
https://www.montgomeryschoolsmd.org/schools/wjhs/departments/world_languages/

It has a link to this page:

For Whitman, it's on the slides on this page (click through the pictures and it shows courses offered in 2023-2024)
https://www.montgomeryschoolsmd.org/schools/whitmanhs/academics/languages/

And for BCC it's similar to Walter Johnson, where their page is here:
https://www.montgomeryschoolsmd.org/schools/bcchs/academics/foreignlanguage/

And has a link to the course offerings here:

How do you know which MS or HS teaches specific foreign languages as electives?
