Whether they made learning fun, supported you through difficult times or inspired you with a newfound passion for a previously unloved subject, their impact will never be forgotten.
These photos show much-loved teachers at schools around Scotland during the 90s.
Some are pictured in the classroom with pupils, others in the head’s office, which you only usually saw when you were in trouble.
This retro gallery also includes a special visit by a big-name TV star, staff and pupils celebrating praise from inspectors, and the official opening of two schools.
