The best evidence of an effective internal control environment is the independent audit results. Independent audit results are the outcomes or findings of an external or independent party that evaluates the design, implementation, and operation of the internal controls. Independent audit results can provide an objective, reliable, and consistent assessment of the internal control environment, and identify the strengths, weaknesses, gaps, or issues of the internal controls. Independent audit results can also provide assurance, recommendations, or improvement opportunities for the internal control environment. The other options are not as good as independent audit results, as they are related to the inputs, processes, oroutputs of the internal control environment, not the evaluation or verification of the internal controlenvironment.
