Data Validation

Data validation is the process of ensuring that a program operates on clean, correct and useful data. It uses routines, often called "validation rules" "validation constraints" or "check routines", that check for correctness, meaningfulness, and security of data that are input to the system. The rules may be implemented through the automated facilities of a data dictionary, or by the inclusion of explicit application program validation logic.

The Certify Rule Library™ is Certica's collection of 160 data validations and alerts which have been gathered from school district implementations of Certify nationwide. The rules, organized by subject area, represent the most widely used, top-priority data validations and alerts applied to data in district information systems – to ensure accurate calculation of FTE/ADA, demonstrate accountability and maximize funding.


The Level Data State Validation Service provides a series of validation rules accessible to users via a custom screen within PowerSchool. The service is designed to help the users proactively correct state reporting errors PRIOR to submission, breaking the cycle of submit, reject, fix, repeat.
