What significant change did the ASB adopt regarding bias in appraisals?

The correct response indicating the significant change adopted by the Appraisal Standards Board (ASB) regarding bias in appraisals is the elimination of vague prohibitions. This reflects a critical development in appraisal standards, as removing ambiguity allows for clearer guidelines that appraisers can follow.

By eliminating vague language surrounding bias, the ASB aimed to enhance transparency and accountability in appraisal practices. This change means that appraisers are better equipped to understand what constitutes biased behavior and how to avoid it, promoting fair and equitable treatment in the valuation process. The move towards clearer, more actionable standards helps appraisers navigate their responsibilities with greater precision, ensuring compliance with ethical and legal requirements.

Contextually, the other options do not align with the ASB's objective to clarify and strengthen standards around bias. Increased fees for bias caseloads would not address the fundamental issues of clarity and compliance; support for bias in certain markets contradicts the goals of fair appraisal practices; and while additional training could be beneficial, it does not directly address the vagueness that existed in previous standards.
