What does "to wait out a full school year" mean?

The setting is in modern day U.S. The character, a teenager, and his mother move places a lot. Then they decided "to wait out a full school year" in a his mom's friend's house in Portland.

I'm not familiar with the U.S school system, so what does it mean? Does it mean they waited for the school year to be over so he can start from the beginning of the new one?

Many thanks.

Solution 1:

"wait out" means to wait until something is over. From M-W

to await an end to

So in this case, they're waiting until the school year is over before moving again. The implication is that they don't want to interrupt the boy's education by moving in the middle of the school term. It's usually easier to start at a new school at the beginning of the term, since everyone else is also starting fresh.
