I have to agree with the parent, that they can’t just jump into the high school Spanish and assume that the child will remember some of the written language prompts.
My children were encouraged to take AP Spanish in high school. (I’m a native speaker. I even took courses in college to “up my game” in written language which, at the time, I didn’t know it would be really necessary in my career.)
At my children’s high school, they had to complete summer assignments to get into the competitive AP classes.
One of those classes was AP Spanish. When I saw the summer assignments, I told them “no”.
Why?
Because I saw myself having to read those novels along with them, so that I could understand the assignment. I didn’t have that kind of time.
I was working full-time.
The summer assignment was ridiculously hard. They were to read and choose from Spanish novels, authored by the original Spanish writers, and complete “compare and contrast” assignments.
I really didn’t have time to help them which I knew I would be stuck doing with them.
I knew they were sharp enough that they would eventually get it. But some of the prompts that I saw, were not my regional Spanish and I was very unfamiliar with the number of South American authors as well as Spanish authors who were listed in the assignment.
My take on this situation is that the OP’s son probably learned some basic grammar, vocabulary and conversational skills.
I really don’t think that throwing a kid into a Spanish class, when he hasn’t been practicing Spanish for at least four years, is beneficial to the student. The family needs to find an equivalent course, somewhere, that can cover the high school/college requirement if they’re that desperate to get into top schools that require foreign language.
My children took Spanish in seventh and eighth grades also but they made sure they reached level four in high school.
Some of their HS assignments were really hard. When they did ask for help I had to ask my mother (their grandmother!), who was also challenged by the academic intensity. She ended up asking her brother, who is a professor in Mexico, for help. The info finally got back to my eldest kid. Turns out she was the only kid who got it right, but it had to go through three people who supposedly speak Spanish well!
I wish the family luck because this isn’t an easy situation and it’s really a little late in the game to figure out that they may be lacking a requirement for one of their schools. I agree look at the CDS data and see if the school that the child wants requires foreign language.
