It's hard to say. Will 1st be a lot different than K? My district K is only 1/2 day, and moving to 1st is a big change.
My son when to a psychologist for about 18 months when he was 12/13. At the time he went for anxiety disorder and social skill problems. Her is borderline ASD, but no professional has ever felt that diagnosis really fits. We stopped the therapy because it started feeling like the sessions were doing anything and we had a natural break, when he was going out of town for a month during the summer. He was also attending a social skills class and that we "naturally" left after a about a year because it felt like he had gotten what he needed out of the program.
Here I am two years later and I'm going to start taking him to a different psychologist who is an expert with Gifted Kids starting next week. The goal is to more work on issue specific to giftedness and his expressive language blocks. So far his social skill continue to improve but they are far from perfect.
I would say trust your gut. What experience does the speech and language therapist bring to the table? Have you been able to meet with them? Do you know what they would be working on? At 15 my son is still slow to warm up to adults and switching who he works with might not necessary go smoothly.
