This was analyzed by comparing the labour market outcomes of the experimental group with the control group. Due to ethical considerations, randomization was not applied to the experiment group, there were no restrictions imposed on participating in the workshops. To establish whether the principle of randomization was adhered to, the mean age of the control group and the PfW group was compared by means of an independent samples T-test, as well as the time they were in the system. Furthermore, the gender distribution was statistically compared through a Chi Square test. As can be seen in Table 1, no statistically significant differences were found between the two groups in terms of gender and age. However, the PfW group appeared to be in the system significantly longer than the control group, arguably representing some extent of self-selection bias. It is therefore questionable whether the control group and the PfW group are completely comparable on all characteristics.

The job matching outcomes of these two groups were mapped into the following possible six categories:
(A) Found a job independently, (B) found a job through the municipality’s career counselors, (C) found a subsidized job, (D) active in basic job searching training, (E) active in advanced job searching training and F) other. Respondents could only be assigned to one of these categories. The “other” group was not taken into account for the following analyses, so 39 respondents (of which 10 from the PfW group) were not taken into account for the further analyses.
Table 2 shows the frequencies of the categories per group. To find out to what extent the relationships between the categories differ between the PfW group and the control group, a comparison was made by means of a Chi-square test. This analysis shows that there are no significant differences between the two groups, ꭓ2 (4) = 8.80, p = .066. However, there seems to be a descriptive difference between the groups.

To check whether the groups differ or whether respondents eventually found work, a variable was created in which the A, B and C categories scored as work found and the D and E categories were scored as no work found. In the PfW group, 30 (37.0%) of the 81 respondents eventually found work and 51 (63.0%) did not find work. In the control group of 190 respondents, 98 (51.6%) respondents found work and 92 (48.4%) respondents did not find work. A Chi-square test was used to compare the extent to which these ratios differ from each other. It appears that the control group found work significantly more often than the PfW group, ꭓ2 (1) = 4.82, p = .028.
There are two possible explanations for the lower job finding rates of the experiment group. First of all, the algorithm-based matching module was not in use for a large portion of the study due to the experienced difficulty of mobilizing employers (it started to see its first use in August, near the end of the experiment). Second, it appears that the self-selection bias present in the control group hinders the comparability of the two groups: the participants in the workshop are arguably facing a larger distance to the labour market. This is reflected by the larger proportion of candidates in the basic job searching category in the experiment group (although the difference is borderline significant). It is important to emphasize that these statistics are descriptive by nature, and that there is no empirical support for establishing a generalizable, “net effect” of the Passport for Work platform in terms of sustainable job matching. However, it can be argued that the platform aides the mobilization of relatively vulnerable job seekers, which facing the highest socio-economic risks.
To facilitate the development of job matching insights at a later stage, a job seeker monitoring system has been established. Through this system, the labour market outcomes of job seekers in the Passport for Work platform can be assessed periodically. The system serves two main functions: improving the algorithm-based job matching (in which a growing number of matches allows for more precise matching criteria) and gaining insight in actual job matches.
