According to the NAHQ CPHQ exam blueprint, the first and most critical step in accreditation readiness is conducting a gap analysis. This involves assessing current organizational practices against accreditation standards to identify areas of noncompliance or risk.

Option B is correct because gap analysis establishes a baseline understanding of where the organization stands and informs prioritization, education, and improvement planning. Without identifying gaps, subsequent activities may be misaligned or ineffective.

Options A, C, and D are important later steps but depend on the findings of the gap assessment. The CPHQ framework stresses that accreditation preparation must be systematic and data-driven, beginning with evaluation before intervention.
