Oooo - I hadn’t heard of Precision Exams. I’ll have to check them out.
I use the Oracle Junior Associate exams for my students who take AP CSA (after Principles) - the junior certifications align pretty well to the CSA exam and its also a lifetime certification for the version of Java they test in. But, the thing that tripped us up last year were the actual logistics of testing. For the CompTIA IT Fundamentals and the Microstoft MTA Exams, you can run those through a less intense PearsonVUE Anywhere Proctored suite - basically you sign up to be a proctor for these exams and you can administer them in your classroom with your students. Takes some paperwork ahead of time, but the actual testing process was straightforward for me. But, for the Oracle exams, students had to actually go to an actual testing center with a specialized proctor. For us in Tucson, that testing center could only fit 2 people at a time and was only open during school hours, which made it pretty unfeasible (infeasible?) for us to figure out how to make this work without doing 10 separate field trips. The whole thing fell apart for us once we realized these logistical challenges.
I guess what I’m trying to say is: before making a final commitment to a certification, it might be worthwhile to investigate the logistics of how students test. If you’re not able to get certified as a proctor or it requires a trip to a specialized testing center, that could be a logistical hardship that you might not be able to overcome on your own.
