Final answer:
The primary drawback of adopting a checklist type project selection model is the difficulty of conducting long-term assessments and planning.
Step-by-step explanation:
The primary drawback of adopting a checklist type project selection model is that it makes it difficult to conduct long-term need and asset assessments, plan for long-term programming, and assess the impact of the project. Since a checklist model focuses on a fixed set of criteria, it may overlook important factors that are not on the checklist but are crucial for the success of the project. For example, it may not take into account the changing needs and preferences of stakeholders or unexpected obstacles that may arise during the project.
