Why don’t we go completely crazy and access the IEnumerable.Where() function instead? $students = @(Import-Csv 'C:\StuGroups\Students.csv').Where({ $_.grade_code -NotIn 'KG','1','2' })

I think you may have been overthinking it a little, is all :). But yes, the key thing is that the MOF doesn’t include a host name. Using the host name as the MOF filename is solely for the benefit of...

No. The formatting system is more or less color-blind, because it needs to work with more than just the console host. If you’re okay with limiting yourself to the console for output, and you’ve named...
