No, summer programs do not give you a boost, nor do many of them even help you get prepared for auditions. Some are very focused on putting on a show or a showcase, so some students have found that a summer program before senior year takes away from audition prep. Some do focus on audition prep and that’s great, but do not think that not doing one will put you behind. My daughter did one before junior year and she loved it, glad she did it, and then the one she was supposed to do last year cancelled and she opted not to do one online. I think you’ll be fine prepping on your own, reading plays, finding monologues you like, taking some voice and dance classes locally if that’s possible and if not, do a few online. You won’t get the experience of what it’s like to go away, and I’m sorry you’re missing out on that because it is a fun experience for high schoolers, but it will not hurt you in the audition process.
