hs graduation diploma/rules in CT

hello, my son graduated hs in central america (end of hs is 11th grade) he recently came to the usa and we put him in his brothers hs to go through 12th grade and graduate so he can be ready for college due to the big difference between scholar systems and for him to know better the system before entering college. We enrolled him in our towns hs he was accepted we showed proof of certificate from the previous hs in central america, after he was accepted and he is a a+ student they want to kick him out of hs because they say he already graduated, we tried to explain that he needs to go through this senior year so he can be accustomed to the system before entering college, because they are very different one form another. can anyone help me and find a law that says my son can stay in his new hs?
thank you

Your son has already completed high school. He does not need to go through senior year in CT because he already has a diploma.

If you had brought this when you first registered him, the school would have told you then that your child cannot enroll because he has already completed high school. You showed the certification after you enrolled him.

The school must discharge him, because he has already completed high school. It does not matter that he did not complete high school in the US. This is why he can no longer attend school in CT.

What do you expect the law to do? The public school system in the US is not responsible for making sure that your child, who completed high school in another country is accustomed to the US system before attending college. He is not and will not be the first student to attend college in the US after completing high school out of the country.

Right now your best bet would be to look into some skill building courses at your local community college if you feel that he he could benefit from improving his skills.

Some of the expensive boarding schools allow students to complete a post-graduate year, especially athletes who will contribute to their team’s success. Otherwise, your best bet would be to look at community college programs. In Connecticut, there are likely to be at least one or two within an easy commute from your home, and possibly even a four-year school (Southern, Western, Central, Eastern) - and they all have staff who are trained to help international students adjust to college. If he applies now, he could start in the January term.
