Hi Rhonda! I love the way Andrew explained the differences JR and Kids versions. Here are a few other points that may help with your decision:The key difference is that JR versions are 60-70 minutes in length and KIDS versions are 30-40. Many middle schools begin with the KIDS versions because of rehearsal time and length. We have a rule of thumb that each page of script equals approximately one hour of rehearsal time.Lengths of musical numbers are usually not shortened for KIDS versions. There are less numbers, not to hurt the integrity of the show.The license includes the materials, student scripts, director's guide, choreography DVD, media disc, rehearsal and acc CDs, costume suggestions, prop suggestions, design suggestions, curriculum guides and show background material. Extra resources available with all kits are audio perusals, production slides, Logo paks, t shirts and video licenses for certain shows.There are definitely shows that are better for certain ages. For example, you probably would not select FAME JR for a k-3 production or Dalmations Kids for a 6-8 show. Some are more difficult musically and some have the challenges with the acting. If you have a title you love, check out the e-perusal and see how the fit for your resources will work. I love to help directors pick shows for their casts. It is 90% of a successful show. Many of our showspace readers, like Andrew, are superb at helping you customize to your kids!Ask us anytime..it is a fun process!
