The History of TRISMS

TRISMS was developed in the late 1980’s by two women who desired to give their children far more than what was available to homeschoolers at that time. 

Linda Thornhill and Sally Barnard had no intentions to write an award-winning curriculum, or to ever publish it, but when others learned what they were doing, they wanted to do it, too.  Thus, TRISMS became a published curriculum in 1990 and, over the years, has become a  complete middle and high school program that fits the classical method and adds research, a unit study approach, and critical thinking skills.

Each TRISMS volume has been a work of many authors.  Before it’s release, each volume has been beta tested in co-ops, homes, charter schools, and various settings in the U.S. and around the world.  Many updates, improvements, and modifications have added to the value of the program.
