The Cub Scout Academics and Sports Program was retired in May 2015; the awards were belt loops and pins. The “New” Cub Scout Program started in June 2015, and has adventure loops and adventure pins. Some of the ideas of the discontinued enrichment program were incorporated into the new program.
As long as they are available to purchase, they may be earned and awarded.
From 2015–2016 Cub Scout Program FAQs, March 6, 2015 Update, page 29:
While the academic and sports program will no longer be supported as a program feature of the BSA after June 1, councils, districts, packs and dens may use the activities associated with the program if it serves the needs of boys. And while inventory remains available, packs and dens may award the devices until the supply is exhausted.
