Does training matter? A meta-analysis and review of caregiver training studies

A review of studies published between 1980 and 2005 shows a significant positive effect of specialized training on the competency of caregivers in childcare (d = 0.45, S.E. = 0.10). Experimental results from the meta-analysis were significantly smaller for settings with no fixed curriculum content, delivery of the training at multiple sites and large-scale programs. Results were also smaller when tests were used that did not align closely with the content of the training. Furthermore, experimental results were smaller for the skills domain, compared to the knowledge and attitude domain. A subset of experiments with both caregiver and child data also showed a positive effect, supporting the causal link between caregiver training, caregiver competencies and child behavior in childcare, although this effect was not significant due to the small number of studies (d = 0.55, S.E. = 0.30). Based on these findings, we advocate the inclusion of instruction related to teacher–child interaction in the curriculum of vocational training for caregivers.
