Can I make students pass a quiz before they get points?

Yes. You set it per student, so you can hold some students to it and not others.

1. Go to Settings and find Rules for one student. Students with their own rules are listed.
2. Find the student (pick All to list everyone, or type a name in Find a student), click their button under Reading counts, and choose:
   • Right away: points arrive as soon as they record reading.
   • After a quiz or your OK: they still record their reading, but no points arrive until they pass that book's quiz or you certify it.
   • When you record it: only you (or another class admin) can record reading for them.
3. To apply one setting to the whole class, click as soon as they record it in "Every student's reading counts as soon as they record it" and pick once they pass a quiz or you certify it or only when you record it. When students already differ, the sentence names them; click Set one rule for everyone instead.

If quizzes start only at school or at set hours (When and where students take quizzes), reading done at home earns its points once the student takes the quiz then.

Whatever the setting, a book above a student's ZPD earns its points only once they pass its quiz or you certify it. See Reading levels and ZPD.

Certifying without a quiz: open the Quizzes tab → magnifying glass on the student → … → Admin certify.
