Sources and methodology
Nothing here is invented. Every statement you answer is traceable to a published, public-domain item bank, and every score is produced by a fixed formula you can check.
How scoring works
Each assessment uses 12 statements answered on a five-point accuracy scale. Positively keyed items score as answered; negatively keyed items are reversed (6 minus your answer). The 12 item scores are summed into a raw score between 12 and 60, then normalised to 0–100 with (raw − 12) / 48 × 100.
No language model is involved in producing your score. AI is used only to phrase reflections on top of numbers that were already computed deterministically.
