Everyone sits the same performance-based assessment. You get an objective read on who can do the work today, broken down by capability, before any training.
Use whatever training fits, your own, a vendor's, or our optional prep. We stay the neutral yardstick, so the improvement is measured the same way regardless of how you got there.
Re-assess and see the movement. Each pass issues a credential anyone can verify, so the uplift is documented and defensible, not self-reported.
A measurement only means something if the people grading it aren't the people who trained for it. Because we don't sell the coursework, the benchmark stays honest, and so does the proof you hand to leadership.
A serious benchmark shouldn't get cheaper because you buy in bulk. Every seat is the same flat rate, whether you certify five people or five hundred.
