Homeschooling High School was my favorite time. I love how my kids all got interested in different things. I thoroughly enjoyed teaching co-op classes and hosting events. I value the time with my teens and their friends.
Below are links for the curriculum we used. Keep in mind that homeschooling high school can look very different from what you have been doing - you can include text books, online classes - both for college credit and other, dual enrollment at the local community college, co-op classes, part time at your local high school - and so much more.
I now have one teen graduated, three teens enrolled in dual enrollment and one teen who has a certificate of completion (due to learning and other disabilities)
