Can you use GCSEs for high school credits in the US?

[MrsPotterings]

My niece is in her GCSE year. Due to family difficulties she may have to move to the US afterwards and we are wondering if there is any point in her taking the GCSE exams. Can she use her GCSE results as "credits" somehow in the US for high school? I don't know anything about the US high school system.

GCSEs are the equivalent of a high school diploma so she may not need to go to high school at all but straight to a community college. You'd need to check with the local school district.

It's certainly worth taking them anyway because they last for life, she may return to the U.K. and plenty of jobs ask for English and maths

It would be ridiculous to not sit them surely, after having done all the work?

Also, if she manages to get into a community college with the GCSEs, she can save a LOT of money on uni, if that's the goal. Community colleges in the states are like mini universities and you can do all your required general ed credits there, before moving onto a proper uni. Uni in the states is 4 years, she can cut that down to 2 if she takes this path.
If she prefers to take a vocational route, depending on the school district, there's much more opportunities there than in a lot of UK areas. This can be a huge blessing for her, rather than a scary situation. Do some research on where she will end up if she does go.

It's a complicated story but my brother is seriously ill and my niece's mother lives in the US. For her to stay to do her GCSEs would mean me moving to london to live with her until the GCSEs are done with all the associated cost and problems that would cause for my own DC. So I really want to know that the GCSEs would be valuable for my niece if she has to move back to the US after doing them.

GCSEs is useful, since not having them when your niece have only a few months seems a shame. US uni uses them as a reference plus other exams. It saves repeating some course modules. Why not get her school involved in the planning, also what did her mocks marks as? If you don’t think it is at a good grade than replan.
