# Accuracy Indicator ### Explanation When issuing a model-based valuation, the model supplier must specify every model-based valuation appraisal value with an indication of the accuracy of the individual concerned taxation. A seven-point scale is used for accuracy, which is based on the probability distribution around the value. The following classification applies: ### Classification

Accuracy Indicator	Definition
0	<50% accuracy in 20% deviation
1	< 85% accuracy in 20% deviation
2	>= 85% accuracy in 10% deviation
3	>= 85% accuracy in 20% deviation and >= 70% accuracy in 10% deviation
4	>= 85% accuracy in 20% deviation and >= 80% accuracy in 10% deviation
5	>= 85% accuracy in 20% deviation and >= 85% accuracy in 10% deviation and >= 60% accuracy in 5% deviation
6	>= 90% accuracy in 20% deviation and >= 90% accuracy in 10% deviation and >= 70% accuracy in 5% deviation
7	>= 95% accuracy in 20% deviation and >= 90% accuracy in 10% deviation and >= 80% accuracy in 5% deviation

Depending on the purpose of the model-based valuation, it is determined which level of accuracy minimum is required. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
