Distinct Count Help

Hi, hoping someone can help, I think it is probably pretty simple, but with my lack of knowledge, I am just banging my head against a brick wall!

I have a table, one column is an assessment ID, there are multiple rows with the same assessment ID.  I have a second column called NCs, there is either a 1 or 0 in that column.  I want to create a measure to count the number of rows with 1 in for distinct assessment IDs.

 

I have something like this, but it's not working!

Audits with NCs = CALCULATE(DISTINCTCOUNT('SQL Ad Hoc'[AssessmentID]),FILTER('SQL Ad Hoc','SQL Ad Hoc'[NCs?]="1" && 'SQL Ad Hoc'[NCs?]="1"))
 
Many thanks

    Can you clarify the desired result please? I don't think this is clear "I want to create a measure to count the number of rows with 1 in for distinct assessment IDs."

    Do you want a distinct count of AssessmentID (with the table filtered for NC = 1)

    or

    do you want a count of NC = 1 rows for each AssessmentID?

    or something else?

    If you provide sample data and show the desired result you will get a better answer.
