This study compares Confirmatory Factor Analysis (CFA) and Smallest Space Analysis (SSA) in assessing motivational values among 364 vocational-education instructors at SENAI-RS, using the Portrait Values Questionnaire (PVQ-20). CFA upheld Schwartz’s ten-factor model, producing satisfactory fit indices and coherent inter-value correlations. SSA recreated the anticipated circular map, showing theoretical clusters and slight overlaps typical of teaching contexts. Both methods aligned on key patterns—strong Benevolence–Universalism cohesion and Autonomy–Conformity opposition—yet revealed subtle distinctions: SSA positioned normative and pro-social values closer than CFA detected. The comparison underscores the techniques’ complementarity, yielding a richer portrayal of educators’ value profiles. These findings can guide teacher-training initiatives, institutional alignment, and value-driven educational policies.
