It truly only takes one minor lapse in memory to create a massive problem. You could have a phenomenal teacher and a wonderfully smooth-running classroom, but if someone forgot to check the master spreadsheet in the office, disaster can strike. Suddenly, you have a staff member with an expired CPR certification sitting alone in a room with ten toddlers.
That is an instant licensing violation if an inspector walks in. Worse than that, it is a massive safety hazard for the children in your care.
Manual tracking with Excel spreadsheets or dry-erase whiteboard calendars is fundamentally designed to fail. Human error is inevitable when you are juggling a million things on a Tuesday morning. Automated compliance tracking takes human error completely out of the equation. Your software should know exactly when a certification expires and force the issue with the employee before it ever becomes a problem.
