Testing, inspection and certification

Testing, inspection and certification are important steps that help to make sure things are safe and working correctly. Testing is like a test in school: it checks to make sure something has the right answer. Inspection is like checking to make sure a toy has no broken parts and everything is the right size and shape. Certification is like getting a sticker that shows something is safe and works properly. These three steps are important because they help us to make sure things are safe and working correctly.
