CVS has recently rolled out a new training program for all new hires. You should have received at least some initial training through your district's pharmacy trainer before you began working in the pharmacy. Most of the PSA training is very basic and you can schedule technician training classes with your trainer through LearnNet.
Your PIC and Lead Technician are responsible for making sure all new hires are scheduled for training. Since its part of the pharmacy execution score, the store will get penalized in execution if you are not certified within a certain timeframe.
