CLEAPSS Supporting technicians

Technicians play a vital role in supporting the teaching of exciting, effective science safely. CLEAPSS provides guidance on all aspects of being a technician and resources such as stock lists, templates for laboratory checklists, requisition sheets, labels and much more to help technicians in their jobs. For help with finding these resources see here. CLEAPSS actively works with other organisations to raise the status of technicians in schools.
