Several of the best-known instruments in this field are commercial products. They are sold under licence, their items are copyright, their scoring keys are trade secrets, and the serious ones restrict administration to practitioners holding specific qualifications. Those restrictions exist for good reasons and we take them seriously.
IVYBootcamps has not licensed any of them, does not claim to have, and does not reproduce their items, their scoring or their branding anywhere in this product. Where a proprietary instrument measures a construct that matters to career guidance, we measure that construct ourselves. That is possible because the constructs are public science — Jung's typology, the five-factor model, Holland's hexagon and the five-index structure of cognitive ability are all published, cited and freely available to build on. What is proprietary is not the idea; it is the particular set of questions somebody else wrote and the norms they gathered.
So the items in this battery were written by our team, the scoring keys are ours, and the norms are ours. The one exception is the five-factor section, where the items come from the International Personality Item Pool: its authors released it into the public domain expressly so that instruments like this one could use it, and we credit it rather than pretending we wrote it.
The practical consequence for a family is worth being direct about. Our instruments do not carry decades of published reliability and validity evidence, because they are new. What they carry instead is a stated construct, an item bank you can ask to see, deterministic scoring, published norms, and validity checks that run on every single submission. We would rather offer that and say so than borrow someone else's evidence by implication.
