Which type of USPAP requirement does not allow for departure from established standards?

The requirement that does not allow for departure from established standards is referred to as "strict." In the context of USPAP (Uniform Standards of Professional Appraisal Practice), a strict requirement signifies that appraisers must adhere closely to the prescribed standards without making any alterations or adjustments based on individual circumstances. This ensures a high level of consistency and reliability in the appraisal process.

Strict requirements often apply to fundamental aspects of appraisal that are essential for maintaining the integrity and objectivity of the appraisal practices. These kinds of requirements are put in place to protect stakeholders and ensure that appraisal reports are credible and can be relied upon for decision-making.

While there are other types of requirements that may allow for some flexibility or adaptation, those deemed strict do not permit any departure from established standards, reinforcing adherence to best practices in appraisal.
