Beginning Early
One way to accelerate during the high school years is for students totake high school level courses prior to the 9th grade year (usually during the 7th or 8th grade years.) The key is to be sure you use high school level materials. In addition, adequately document the high school course by keeping good records of the resources used (including textbooks, DVDs, videos, additional reading, etc.), the
amount of credit you gave the course, your method of evaluation (tests, quizzes, papers, etc.), work samples from the beginning, middle, and end of the course to show progress, and also the final letter grade that you awarded your child. Most colleges do not have a problem with high school level courses taken in the 8th grade, but some colleges may have strict policies of not counting for high school
credit any course taken prior to 8th grade. So please check with colleges your teen is thinking about applying to in order to ask about their policies regarding courses taken prior to 9th grade.
Speeding Up
Some teens cover course material very quickly and may be able to finish the material early. If that is your experience, then you have the option to begin another course mid-year. For example, if your teen flew through the Algebra 1 book in one semester (and you are sure he or she has mastered all of the concepts), then go ahead and start the Algebra 2 book. In general, when you put together your transcript, you will want to include the course in the year it was completed. So, if the Algebra 2 course was started in the 9th grade,
but finished in the 10th grade, then show the Algebra 2 course in the 10th grade year on the transcript.
Finishing in Three Years
Some teens may want to (and are capable of) finishing up their high school requirements in three years instead of four years. However, here are some questions to think through:
Is my teen ready for the real world in terms of not only,academic ability but also spiritual and emotional maturity? Are there any age restrictions that come into play for his or her next step after high school graduation (such as licensing requirements, apprenticeship programs, employment opportunities, and so forth)? Although your teen may have completed the minimum courses necessary for high school
graduation, could the traditional 4th year of high school be used to take additional and more advanced courses that will better prepare him or her for adulthood?
