PBL Signs and Values signage are an integral part of any modern educational environment. The practice of placing, in bullet-point format, five to ten key PBL (positive behaviour and learning) or key values in public places is taking hold in the business world also. Schools have long used this mode of communication for teaching and learning within the classroom, however PBL signs and messages are increasingly displayed on colourful, permanent signage and are strategically placed to reinforce core values and expectations.
