Inconsistent staffing and its impact on service delivery in ASD early-intervention.
Stable teams are a hidden treatment variable—protect them or lose fidelity.
01Research in Context
What this study did
Sulek et al. (2017) talked to staff in preschool autism programs. They asked how constant staff changes affect the quality of teaching.
The team used interviews and focus groups. Staff shared real stories about kids losing skills when yet another new aide walked in.
What they found
Workers said high turnover breaks the flow of lessons. New people do not know each child's program, so errors creep in.
Casual or float staff feel lost. Without steady teammates, they skip steps and kids make slower progress.
How this fits with other research
Lushin et al. (2020) counted teaching moments in classrooms. They found that more aides can actually cut one-to-one ABA time when roles are unclear. Rhylee's staff voices help explain why: newcomers do not know the plan.
Cymbal et al. (2022) tracked 1,000+ ABA employees. Low pay and upset families predicted technician turnover, backing Rhylee's worry with hard numbers.
Townsend et al. (2024) show a fix. Six agencies kept staff and quality high for ten years by setting clear roles, training loops, and parent feedback. Their system supersedes the problem Rhylee flagged.
Why it matters
You can guard your program against the drift Rhylee describes. Start by mapping who does what each session. Add a 15-minute daily huddle so new floats hear the plan. Track parent satisfaction; Cymbal links low scores to exits. Over time, build the full system Townsend outlines—training, feedback, and fair pay—to keep your team stable and your kids moving forward.

03Original abstract
BACKGROUND: Inconsistent staffing (high turnover, casual workforce) is problematic in organisations, with the potential to impact both staff and services provided. Research has primarily focused on the impacts of inconsistent staffing in child welfare and community services with little evidence surrounding their ability to impact the outcomes for children with Autism Spectrum Disorders attending early-intervention services. AIM: The aim of this study was to explore staff views regarding the impact of staff turnover on the delivery of group based early intervention for children with ASD. METHODS AND PROCEDURES: We conducted five focus groups involving 29 professional (e.g. teachers, behaviour therapists), para-professional (e.g. child care workers), and managerial staff to explore their views. Audio recordings were transcribed verbatim for use in thematic analysis. OUTCOMES AND RESULTS: Two central themes, comprising five categories emerged to encompass participants' views. "Impacts on Staff" accounted for the challenges existing staff felt when working with new and untrained staff in the centre. Participants also expressed concerns for the "Impacts on Service Delivery" that resulted from dynamic staffing, affecting fidelity of interventions and the program itself. CONCLUSIONS AND IMPLICATIONS: The findings suggest that lacking a consistent staffing structure is problematic when attempting to provide high quality early intervention services to children with ASD and suggest that future research should investigate the extent of inconsistent staffing, impacts of inconsistent staffing on providing intervention, and develop a range of tools to help measure these effects.
