# Accuratesse Indicator

### Uitleg

Bij het afgeven van een modeltaxatie dient de modelleverancier iedere modeltaxatie taxatiewaarde te specificeren met een indicatie van de juistheid van de betreffende belastingheffing. Voor de nauwkeurigheid wordt een zevenpuntsschaal gebruikt, die is gebaseerd op de kansverdeling rond de waarde. De volgende classificatie is van toepassing:

### Klasses

<table><thead><tr><th width="196">Accuratesse Indicator</th><th>Definitie</th></tr></thead><tbody><tr><td>0</td><td>&#x3C; 50% accuratesse in 20% afwijking</td></tr><tr><td>1</td><td>&#x3C; 85% accuratesse in 20% afwijking</td></tr><tr><td>2</td><td>>= 85% accuratesse in 20% afwijking</td></tr><tr><td>3</td><td>>= 85% accuratesse in 20% afwijking en >= 70% accuratesse in 10% afwijking</td></tr><tr><td>4</td><td>>= 85% accuratesse in 20% afwijking en >= 80% accuratesse in 10% afwijking</td></tr><tr><td>5</td><td>>= 85% accuratesse in 20% afwijking en >= 85% accuratesse in 10% afwijking en >= 60% accuratesse in 5% afwijking</td></tr><tr><td>6</td><td>>= 90% accuratesse in 20% afwijking en >= 90% accuratesse in 10% afwijking en >= 70% accuratesse in 5% afwijking</td></tr><tr><td>7</td><td>>= 95% accuratesse in 20% afwijking en >= 90% accuratesse in 10% afwijking en >= 80% accuratesse in 5% afwijking</td></tr></tbody></table>

Afhankelijk van het doel van de modelmatige waardering wordt bepaald welk niveau van nauwkeurigheid minimaal vereist is.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.altum.ai/taxeren-en-waarderen/woningwaarde-api/accuratesse-indicator.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
