Katanning Senior High School runs a transition program each year for the students from feeder primary schools which begins in Term 2 and continues in Term 4. The program includes an Academic Extension Program, school visits by KSHS staff to the primary schools, primary school classes visiting KSHS on designated Transition days and the Orientation day for all incoming Year 7 students.

The Academic program means students, who have been chosen by their school, are introduced to specialist facilities and equipment in the Science, Humanities and Social Sciences (HASS) and Design and Technology areas. It is a half day program and students are picked up in the KSHS school bus and dropped back at their school in the afternoon.

Teachers from KSHS visit feeder primary schools and team teach with the classroom teacher for half a day. This allows students to get to know someone at the high school.

During Transition in weeks 5, 6 and 7 of Term 4 each feeder school is allocated a particular day in the week and their teachers bring the incoming students to the high school where they are involved in an educational program taught by KSHS school staff in a secondary setting.

In Week 8 of Term 4 all of the schools combine for Orientation Day. On this day the students are placed into their new forms and participate in a day where they are moving classrooms and being taught by the KSHS staff.

A Parent Orientation morning is held on the same day and parents are introduced to Student Services staff, briefed on the changes that will occur for their child when they enter Year 7 and given a tour of the school before a morning tea where they meet the teaching staff.
