Core concepts
Concept 1
Comparable Selection, Units, and Adjustments questions reward the answer that follows the official source, the professional role, and the stated facts.
Exam cue: Identify the candidate role, client or public risk, source rule, calculation, or process step being tested.
Concept 2
The strongest answer identifies the rule, safety concern, ethical duty, calculation, client factor, or process step before acting.
Exam cue: Check whether the fact pattern is using a national standard, jurisdiction rule, handbook policy, or scenario-specific instruction.
Concept 3
Eliminate answers that ignore requirements, skip documentation, overreach the role, or treat convenience as the standard.
Exam cue: Choose the compliant and professionally scoped answer before the convenient or familiar answer.
Risk pitfalls and guardrails
Treating related standards as interchangeable without checking the source.
Guardrail: Avoid answers that rely only on habit, ignore the stated source, skip safety or compliance steps, or choose convenience over the professional standard.
Skipping screening, documentation, authorization, sanitation, recordkeeping, or other required procedure.
Guardrail: Avoid answers that rely only on habit, ignore the stated source, skip safety or compliance steps, or choose convenience over the professional standard.

Memory anchors
Comparable Selection
Comparable selection prioritizes similarity, relevance, verification, and market behavior.
Unit Comparison
A unit of comparison expresses price in a market-recognized unit such as per square foot or per unit.
Transactional Adjustment
Transactional adjustments address rights conveyed, financing, conditions of sale, expenditures, market conditions, and sale conditions.
Property Adjustment
Property adjustments address location, physical features, economic attributes, use, and nonrealty components.
Paired Data
Paired data isolates one difference between otherwise similar sales to support an adjustment.
Cost Analysis
Cost analysis can support an adjustment when market evidence supports the cost relationship.
Trend Analysis
Trend analysis studies market movement over time for market condition adjustments.
Verification
Verification confirms sale facts, motivations, conditions, and data reliability.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
