Abstract

The purpose of this study is to systematically review and compare the measurement properties (reliability and validity) and application scope of five commonly used intelligence assessment tools for children: WISCV, SB-5, RPM, KABC-II, and UNIT-2. Using a systematic literature review combined with a comparative analysis approach, the study synthesizes and objectively evaluates academic evidence related to these five individual intelligence scales. The results indicate that WISCV, SB-5, and KABC-II are comprehensive tools with high reliability and validity, suitable for clinical diagnosis and specialized educational interventions. In contrast, RPM and UNIT-2 demonstrate advantages in large-scale screening and assessment of specific populations due to their nonverbal nature and cultural fairness. The study concludes that selecting the most appropriate tool should be based on specific assessment objectives, individual child characteristics, and contextual factors, while emphasizing the critical role of professional expertise in interpreting results.
