A sticker chart is a behavioural reinforcement system in which students receive stickers or visual markers when they meet certain expectations. The chart typically tracks behaviour over time and may lead to rewards when specific goals are reached. Sticker charts are commonly used in early childhood and behavioural support programs to encourage desired behaviours through visible recognition. While some educators find them useful for reinforcing routines, critics note that such systems may focus heavily on external rewards and compliance rather than addressing underlying needs or supporting intrinsic motivation.
