           CompletionDate = $CompletionDate
           CertificationScore = $CertificationScore
           ComplianceStatus = if ($CertificationScore -ge 80) { "Compliant" } else { "Non-Compliant" }
       }
   
       # Send to Log Analytics workspace
       Send-AzMonitorLog -WorkspaceId $WorkspaceId -LogData $logData -LogType "PCITrainingCompliance"
   
       # Update user's training status in Azure AD
       Update-AzADUser -ObjectId $UserId -ExtensionProperty @{
           "PCITrainingStatus" = $logData.ComplianceStatus
           "LastTrainingDate" = $CompletionDate
