My husband and I worked abroad and the frequent moving was disruptive to education. In order to get my son in kindergarten in a private foreign school, he had to be able to read at level K-5 and meet other criteria. I had only the Christmas break to teach him and get hims through the K-4 material as he had never had any pre-school or kindergarten. They gave me American home-school material. It was my first experience with home schooling. I had a very busy schedule but was astounded that we got through the materials and he excelled, started with the rest of the class after the break and moved along on task. After first grade, we moved again. I purchased materials for 2nd and 3rd grade and worked with him. Keep in mind that many materials are workbook format and are self-paced. In other words, you have a minimum amount of work that MUST be covered to stay on task. In homeschooling, the advantage over the traditional classroom is that students can work ahead in subjects that they have a natural aptitude for or a keen interest in. In subjects that are more challenging, you have time to slow it down, gain understanding and learn the material. Done prudently, this prevents the "gaps" in learning that many students are disadvantaged by. In a traditional setting, if your are "bad" in a subject, you take the minimum requirement for graduation or a degree program and are thankful it's out of your life. In homeschooling, students learn that with instruction, time, and practice, they can master anything they set their minds to do. My son loved homeschooling. When we settled again he was tested at a private school and moved a grade ahead(skipped a grade level). At 10,000 a year tuition, the time I had invested paid for itself, which was a benifit I had not anticipated.
We spent about 3 hours a day in the lower level grades. Naturally the investment of time increases in middle school and then for many, drops again in high school or when the student is savvy enought to go online for lectures and tutorials.
There are also wonderful co-ops where you can join other homeschoolers for art, music, sports, field trips, science unit studies, travel, and lots or enrichment classes that allow them to interact with other students.
Living off-shore, I saw many American kids of expatriates complete high school and two years of college as independent students at age 17 or younger. Look at the numbers for home-schooled students getting into Ivy League colleges. Getting a couple years of college under your belt and earning schlorships has a tremendous value. The discipline that students learn through homeschooling (under dedicated parents)and the rewards of achievment give them a great advantage in the competitive world we live in.
Bottom line, it is a serious committment on the part of parents ( dad can help) but the educational benifits and advaantages to the student are worth it.
Cobb County has a huge homeschool community and excellent resources. I would imagine other counties do as well. Good luck with whatever decision you make.
