Participants who complete a PAREA program for the LR credential earn 67% experience credit for the CR credential. It’s up to each state to decide if the remaining 33% can be earned through the traditional supervisor-trainee experience model to fully satisfy the CR experience requirement.
Some states will require the completion of CR PAREA if LR PAREA was previously completed. Those states will not allow a combination of LR PAREA + 33% traditional experience to satisfy the CR experience requirement.
You should check with your state regulatory board or authority to determine their requirements.
