High School Open House! On Thursday, April 19th, Sure Foundation Homeschool Tutorial will hold an Open House for all high school level classes. If you will have a high school student in the coming school year, stop by between 8am and 12:30pm to observe our classes, meet teachers and co-op families, and find out how Sure Foundation can help you homeschool through high school. Registration for high school classes is open for new and returning families, and there are openings in all high school level classes. (Middle school level classes are full at this time.) Questions?
