Middle/High School building includes grades 7-12. Grades 7 and 8 comprise SFIS Middle School. The High School covers 9-12.
Both schools are separate for attendance and grading purposes, but are located in the same building. High School is administered by Principal Mr. Eustace Night Shield and Middle School is administered by Ms. Wendy Castaneda-Leal.
The Office Secretary, Paula Whiting, is the primary contact for all 7-12 matters. Ms. Whiting deals with 7-12 student issues, but can assist any parent or guardian to get to the proper person on their concern. She also handles 7-12 staff attendance matters.
