Which software? That's critical. The offering from X-rite isn't best in class but netiher are the two dispalys you're working with so yes, that might be as close as you get.
You will probably have to futz around with different settings to get the two to match. IOW, don't expect that you'll use identical settings for white point, cd/m2 etc for both to produce a visual match.
The basic concept is the same in trying to get a print and display to visually match. The correct settings are those that produce the match. A guide to how to fix this:

That might be too low for the units to natively hit that value. Depending on the display, it's age etc, that's a really low value to hit and may be part of your problem. Try 150cd/m2. You can try moving lower from there (although I don't know why you'd want such a low value).

The warm/cool axis should be addressed with White Point target calibraiton settings but magenta/green is the opposite color axis and I don't know how well that can be fixed depending on the software you are using. Some products have only control over the other color axis.

That's a good sign.

Other than the location, the two sets of displays, calibration, ambient lighting and print viewing conditions are identical? Sure the students are not adjusting the OSD controls?
