The Certification Frequency setting indicates the frequency at which a participant is expected to provide certification to verify eligibility. The system automatically compares case certifications to the certification frequency and displays an informational message when the certification period does not align with the certification frequency. For example, if the certification frequency is set to 'Day 1 of every 1 month(s)' and the certification period entered only covers a two week period, an informational message will be displayed to alert the caseworker that the period of the certification is different to the certification frequency.
