# CQM Scoring - Quality Measure Implementation Guide v2.0.0-ballot

## Extension: CQM Scoring 

Indicates how the calculation is performed for the measure, including proportion, ratio, continuous-variable, and cohort. The value set is extensible, allowing additional measure scoring types to be represented. When present on a group, specifies the scoring to be used for this group, overriding the scoring specified for the overall measure.

**Context of Use**

**Usage info**

**Usages:**

* Use this Extension: [CQM Composite Measure](StructureDefinition-cqm-compositemeasure.md), [CQM Computable Measure](StructureDefinition-cqm-computablemeasure.md), [CQM Continuous Variable Measure](StructureDefinition-cqm-cvmeasure.md) and [CQM Ratio Measure](StructureDefinition-cqm-ratiomeasure.md)
