Absolutely!  The main idea behind our programs is to give you new skills, abilities and a peer network to accelerate your professional growth.  So, you can start either our A-CSM, A-CSPO, CSP-SM or CSP-PO programs even if you do not have the required work experience yet, but you cannot have your certification issued until you obtain the required length of work experience and have updated your work experience on your Scrum Alliance profile.  Why wait to level up on your talents?
