Parent question
Group speech therapy: is it enough?
Published · Updated
The short answer
Group therapy can work. The one trial in a major review that compared group and individual speech therapy found no difference in results, and a newer study found a group treatment effective. But the evidence is thin, and in bigger groups each child gets fewer practice tries. School speech-language pathologists (SLPs) had a median caseload of 50 students in 2024, so groups are common. Practice at home can add the tries a group session can’t.
What the research says
- In a 1966 trial of 216 school-age children, group and individual therapy led to similar results for speech sounds (Sommers et al., 1966, as analysed by Law, Garrett & Nye, 2003). That’s one old study with mild to moderate difficulties.
- In a 2016 study of 28 children aged 6 to 9, a motor-learning treatment given in groups of up to four helped children learn their target sounds within 40 half-hour sessions, compared with no treatment (Skelton & Richard, 2016).
- In a study of 90 school SLPs, children in bigger groups got fewer practice tries each (Farquharson et al., 2022).
- A review of school service delivery models found too little research to say which works best, and advised SLPs to rely on their own data (Cirrin et al., 2010).
Why groups are common
- Large caseloads. In ASHA’s 2024 Schools Survey, full-time school SLPs had a median of 50 students, against a median of 40 they considered manageable (ASHA, 2024).
- Shortages. 79% of school SLPs said there were more job openings than job seekers, and 26% named a shortage of SLPs as the biggest barrier to a manageable caseload (ASHA, 2024). Jobs for SLPs are projected to grow 17% from 2025 to 2035 (BLS).
- Groups make room. ASHA notes that large caseloads may mean shifting from individual to group therapy, and to bigger groups. In a survey of almost 2,000 school SLPs, students with moderate to severe difficulties were typically seen 2 to 3 times a week for 20 to 30 minutes in groups outside class, and caseload size seemed to drive these choices more than students’ needs (Brandel & Frome Loeb, 2011).
Caseload rules
- ASHA doesn’t recommend a specific caseload number, because no research supports one. It encourages a workload approach that counts all of an SLP’s duties, such as a 3:1 model: three weeks of regular sessions, then a week with more flexible scheduling for other direct and indirect services.
- Some states set limits. California caps the average caseload for school speech specialists at 55 per local area, unless the local plan sets a higher average and explains why (California Education Code § 56363.3).
- Some districts use speech-language pathology assistants to help. See what an SLPA is.
Questions to ask the school team
- How many children are in my child’s group, and are they working on similar goals?
- About how many practice tries does my child get in a session?
- How often, and for how long? Your child’s IEP must state how often and how long services happen (34 CFR 300.320).
- How is progress measured, and how often will I hear about it?
- What can we practise at home, and at what level?
If you think your child needs more, you can ask for an IEP meeting to discuss it. See school vs private therapy.
Making the most of group therapy
- Add short practice at home with the words from therapy. See practice at home and speech practice games.
- Keep a practice log and share it with the SLP.
Questions parents ask
Is group speech therapy as good as individual therapy?
The little research there is found similar results, but it’s limited and mostly old. In bigger groups, each child gets fewer practice tries, so group size matters.
How many kids are in a speech therapy group?
It varies by school, and there’s no national standard. Ask your child’s SLP how many children are in the group and whether they’re working on similar goals.
Can I ask for individual speech therapy at school?
You can ask. Services are an IEP team decision, and you’re part of that team. Bring any data you have, like a practice log or recordings, to the meeting.
