TheAICP Code of Ethics(2022), Section A, Principle 3(c), encourages planners to “share the results of experience and research that contribute to the body of planning knowledge.” Option A (share the results with proper credit) aligns with this principle, promoting knowledge-sharing while respecting authorship. Option B (require reimbursement) is not mandated by the Code and may hinder professional collaboration. Option C (withhold the study) violates the principle of sharing knowledge. Option D (send to the local government) bypasses the consultant and lacks transparency. TheCPC Study Manual(2024) states, “The AICP Code encourages sharing research results with proper attribution, fostering professional collaboration,” supporting option A.
