If you are up for it, have them tryout next Spring with any travel team for the 26-27 season. They let kids play a year up all the time and they will develop a lot.
Otherwise, I would supplement with purposeful "ball mastery" clinics for kids in their age group.
-The reason for this is to have a program actually teach them specific moves and ball skills like, Scissors, Mathews, L-pull, Cruyff Turns, Double Scissors, Push-Pulls ect.
This is our 5th year of travel and we have had 4 different coaches and 6-8 substitute coaches in this area and 80% of the younger coaches don't know how to coach these skills. They often do not put the strongest coaches in charge of the younger teams and it is 100% dependent on the Coach. And you will not know who the Coach really is until next later Summer/ Early Fall when the season starts.
Despite what all the Clubs advertise on their websites...development, licensed professional coaches, championships, agility training ect. It is all non-sense and goes out the window when your kid gets some Coach who is only coaching to get a discount for their kids who are already in the program. And/ or, we have have a former youth national team member as a coach...and they do not develop kids and constantly plays kickball. "Kick it long to the striker or long GK punts!"
Starting a year early is great, but you have to supplement with clinics (Coerver, HP Elite, Capstone, Futstars, GoldenBall) to learn developmental skills.
We left one club in South Alexandria, who literally only had 1 dedicated coach to teach these skills to the young players, 1x per week for 8 weeks (to 60 kids at a time). It barely sank in, then the regular coaches would mostly scrimmage the kids the rest of the time and not require skill moves at all.
But, when we went to clinics, the Coaches would actually teach and skills moves in small groups and get the repetition in. And any kid who was really good in travel, always learned skills outside of travel.
-Sorry this was a long and it as just my 2 cents.
