<p>If your child do end up going to a new school junior year, make sure you get her transcript transferred properly. I know most private schools do not rank or calculate GPA, but find out how/if they would normalize your kid’s grades from a public school. My kid transferred from an US private to an international school junior year. We had a hard time with her transcript. At the end it was an excellent experience for her, but it did take her few months to get accustom to her new school, and she lived at home. Since she was our second child, we knew the importance of LORs, so both she and I made a point of getting to know her teachers and counselor(s) well. </p>
<p>If your kid is going to a good public in NJ and is doing well, I would not switch her out junior year. My kids went to a very good day school in NJ. They had a lot of new students 9th grade, and it was hard for some of those students to keep up due to rigor of course work, but by 10th grade most of them do catch up. I think it would be very hard for your D to be top at a BS by coming in junior year, and ultimately that may hurt her college application.</p>
