Student information systems for K-12 schools covering enrollment, attendance, grades, and parent communication. Right now, PowerSchool is the brand AI assistants recommend most, with a Visibility Score of 63 and the #1 spot in 47% of answers. Head-to-head: PowerSchool vs Infinite Campus →
These rankings are measured from what the three models know from training, not a live web search. When the models DO search the web, see which sources they cite. Methodology.
Three models, three different opinions on who leads K-12 SIS.
PowerSchool wins the overall index at 62.5, but that headline hides a genuine three-way disagreement: Claude strongly favors PowerSchool at 76.3, ChatGPT parks it at 65, and Gemini drifts toward Alma at 62.9 while scoring PowerSchool a full 16 points lower than ChatGPT does. Alma is the sharpest illustration of the split, sitting third overall despite never being picked first, because its Gemini score outpaces its ChatGPT score by nearly 4 to 1. Any vendor optimizing for one model's preferences is essentially ignoring how the other two frame the category.

The ± under each score is the reliability band: how much the number would move if we re-ran the identical measurement. It is tight because each prompt is sampled multiple times. It is not the same as how much the ranking depends on which prompts we ask — a separate, wider figure shown on hover.
Just below the cutoff: AWS (4), Microsoft Entra ID (3.9), Jupiter (3.5), Remind (3.5), Okta (3.5). 75 brands were scored in this category; the leaderboard shows the top 15.
Visibility Score: position-weighted presence across all measured answers, 0 to 100. A score of 100 means the brand was the first recommendation in every answer. Every point in a trend line is a live monthly measurement; there is no modeled or backfilled history. Full methodology.
Openness 38/100: the share of this category's recommendation weight not held by the leader.
