As the importance of verification and validation(V&V) activities is growing, the necessity of criticality-based assessment framework of V&V capability is increasing in the safety-critical software organizations. Although several maturity models for quality improvement, such as Capability Maturity Model Integration (CMMI) and Testing Maturity Model (TMM), were developed following the industry?s request, they have the limitation to support enough V&V assessment for the safety-critical software. In this paper, we propose the framework of V&V capability assessment in order to assist in performing "safety-criticality" assessment. To provide the essential V&V practices and the confidential capability level scheme, our framework has five V&V capability levels based on the integrity level scheme of IEEE Std.1012 and the V&lV tasks that come from IEEE Std.1012, 7-4.3.2, 1228, RG 1.168, and CMMI.
