You need to look at the requirements within your district if you are considering a grade skip. In our district a student is required to pass the reading, math, science and social studies credit by exam tests with at least an 85%. Most advanced students do not have problems with the reading and math but the social studies and science test can hold them back simply because they may not have been exposed to the material. In this circumstance, it may be necessary to teach some of the material at home before taking the test.
