How families choose at this level
The final school years are chosen almost entirely on university outcomes: which specialisation tracks exist, how exam preparation is handled, and where graduates actually got in. Families compare schools on this and cannot find it, because schools publish general descriptions rather than placement records. Students are the second audience and are usually ignored entirely, even though at this age they are often the ones deciding.
What we build for a high school
First, specialisation tracks with subjects and where each leads, since that is the choice being made. Second, university placement records published, the most persuasive thing a high school can put on a page. Third, exam preparation described concretely: hours, format, who teaches it. Fourth, a student and parent portal with grades, attendance, mock exam results and deadlines, because the final years run on deadlines nobody can afford to miss.
