Hosanna Preparatory school opened its doors in September 1999 as Horizon Preparatory School, but was asked by the Ministry of Education to change the name since there was already a school in Kingston registered under that name.
Linette Redway, Principal at the time, had a vision. She woke up at 3 a.m. and shared it with her husband, Reverand H. Redway. She asked him what Hosanna meant in the Bible. He told her: "Praise to God". She came to school and told us about the vision she had, and that was how the school got its name, HOSANNA PREPARATORY SCHOOL.
