An important pillar of the evidence base of career education practice is formed by a series of meta-analyses of career intervention studies, published over the last 30 years. These studies have measured the impact of career interventions and explored the influence of different intervention methods and approaches (Baker & Taylor, 1998; Brown & Roche, 2016; Brown & Ryan Krane, 2000; Brown et al., 2003; Oliver & Spokane, 1988; Whiston, Brecheisen, & Stephens, 2003; Whiston et al., 2017; Whiston, Sexton, & Lasoff, 1998)..

In these studies, what makes a "career intervention" is defined broadly, as any effort made to improve clients’ career development, which is most often measured as career maturity, career decision-making, vocational identity, or perceptions of environmental factors. Career interventions can be individual or group counselling, workshops, career development classes, the provision of career information and self-help resources, or computer-based or -assisted activities.

These meta-analyses have consistently found that career interventions do indeed help people, to a moderate but statistically significant degree. In the most recent study, Whiston et al. (2017) reported that on average, participants in a career intervention had a 60% chance of attaining a higher outcome measure than members of the control group who didn't participate in the intervention, a finding consistent with those of previous studies. These studies have also found that repeated interventions are more effective than one-off interventions, group interventions are as effective as individual interventions, and interventions that are facilitated by an expert career development practitioner are more effective than those that are not.
