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

## Resource Profile: CQM Composite Measure 

 
The CQM Composite Measure Profile describes minimum expectations for a composite electronic Quality Measure (QM). For more information on the usage of this profile, refer to the Profiles and Packaging pages in this implementation guide. 

**Usages:**

* Examples for this Profile: [PreventiveCareandWellnessAllOrNothingComposite](Measure-PreventiveCareandWellnessAllOrNothingComposite.md), [PreventiveCareandWellnessOpportunityComposite](Measure-PreventiveCareandWellnessOpportunityComposite.md), [PreventiveCareandWellnessPatientLevelLinearComposite](Measure-PreventiveCareandWellnessPatientLevelLinearComposite.md) and [PreventiveCareandWellnessWeightedComposite](Measure-PreventiveCareandWellnessWeightedComposite.md)
