The purpose of this pilot study was to test the reliability of a game-based assessment tool to assess the four dimensions of career adaptability (i.e., Curiosity, Control, Confidence, Concern, hereafter called “4C”) among students with special educational needs (SEN). The 4C tool is a board game developed in relation to the short form of the career adaptability scale (CAAS) for SEN adolescents. Unlike self-reported CAAS without specifying career-related scenarios, the board game provides researchers and practitioners with an assessment platform to evaluate SEN students’ 4Cs in multiple employment-related scenarios. Participants in this pilot study were 44 secondary school leavers with SEN. They were studying in a training course organized by Youth Academy for SEN. They were assessed through the board game assessment tool before and after the training in the year. Statistical analyses included spearman’s rho coefficient and intra-class correlation coefficient (ICC). It was noted that the 4Cs assessed by the board-game are 1) positively correlated with each other (correlation coefficients ranged from .42 to .63, p<.05), 2) with good inter-rater reliability, rs= .688(92), p<.01, 95% CI [.565, .797], and 3) with moderate test-retest reliability, ICC = 0.66, p<.001, 95% CI [.433, .805]. These findings supported the reliability of this game-based assessment tool for assessing the 4Cs of SEN youths. Aside from self-reported data, this game-based assessment tool can provide supplementary information on the 4Cs of school leavers with SEN from other assessors (e.g., teachers and practitioners) across career-related scenarios. The presentation will further discuss limitations and further direction of research. Copyright © 2023 The Education University of Hong Kong.
