• Validity Generalization (VG) matured as a formal methodological program, integrating Monte Carlo testing, artifact distributions, and population-true validity estimates, with meta-analytic synthesis and critical scrutiny shaping practice [6] [7] [4] [1] [5] [10] [12] [17].

• External validity and cross-context generalization dominate debates on transferability of validity evidence across education and work settings, with The Concept of External Validity [13], Generalization of SAT Validity Across Colleges [8], Validity in Evaluation Research [14], and Assessment Centers and Content Validity [16].

• Educational validity and assessment-centric issues emphasize domain-specific validity criteria and measurement contexts, including Educational Validity Revisited [15], Assessment Centers and Content Validity [16], Generalization of SAT Validity Across Colleges [8], and A Study of Hypotheses Basic to the Use of Rights and Formula Scores [11].

• Fairness, bias, and alternatives in employee selection highlight validity with adverse impact concerns and exploring alternative procedures; key works include Validity and Fairness of Some Alternative Employee Selection Procedures [3] and A Study of Hypotheses Basic to the Use of Rights and Formula Scores [11].
