The age groups listed here are defined in Admin / Program / Age Groups. By default these age groups are defined according to Alberta Child Care Licensing standards, and these are the same age groups that are used to calculate real time ratios in each room, so make sure that if you change these age groups they match the licensing standards in your region.
Automatically Calculate Part Time Fees
At the top of the page is an option to "Automatically calculate part time fees". With this option enabled, anytime you enter or change a Full Time fee, the rest of the fees for that age group or room (4 days p. week, 3 days p. week, etc.) will be automatically calculated and populated.
