When requesting shifts, you will often see what is called a compliance list. These are a list of credentials that is required by that facility in order to work in their building.
On these lists there is also a percentage showing how compliant you are to the given facility. You do not have to be 100% in order to request that shift - you can be 0% compliant and still request the shift. It is then the facility’s decision on whether they will accept the request or not without the credentials they require but you have a much higher chance of getting accepted to work the shift if you are more compliant!
