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.
Do these photos bring back any memories for you, and is your favourite teacher pictured? If you enjoyed these pictures, you might like this look back at memories of school life in the 80s.
