Quiz: Mentors, Students, and the 3:1 Ratio

Test your understanding of mentor and student roles, the three kinds of mentors, why the 3:1 ratio works, and how to add and group mentors and students responsibly with these review questions.


1. What is a peer mentor?

  1. A software professional who volunteers occasional guest sessions
  2. An older student, typically a teenager, who mentors younger students and often explains concepts in kid-to-kid language
  3. Any adult who has completed a background check
  4. A parent who only attends sessions to observe, not to teach
Show Answer

The correct answer is B. The chapter defines a peer mentor as an older student, typically a teenager, who mentors younger students -- less technically experienced than an adult mentor but often better at explaining concepts the way another kid would understand. Option A describes a professional mentor instead. Option C describes the general screening requirement for adult mentors, not the peer mentor's defining trait. Option D describes an observing parent, unrelated to any mentor type.

2. What does the student to mentor ratio measure?

  1. The percentage of students who return for a second session
  2. The number of years a mentor has volunteered compared to a new mentor
  3. The number of students each mentor is responsible for during a session
  4. The ratio of professional mentors to volunteer mentors in a club
Show Answer

The correct answer is C. The chapter defines the student to mentor ratio simply as the number of students each mentor is responsible for during a session, with 3:1 as the recommended target. Option A describes a retention metric, unrelated to supervision ratios. Option B describes mentor tenure, not a student-supervision measure. Option D describes a mentor-type mix, a different comparison than the student-to-mentor ratio.

3. What is mentor capacity planning?

  1. Designing the curriculum tracks a professional mentor teaches
  2. Scheduling which day of the week the club meets
  3. Deciding which mentor type -- volunteer, professional, or peer -- to recruit first
  4. Calculating how many students the club can responsibly serve given its current mentor count
Show Answer

The correct answer is D. The chapter defines mentor capacity planning as calculating, at any point in time, how many students the club can responsibly serve given its current mentor count, recalculated whenever a mentor joins or leaves. Option A confuses this with curriculum design, a separate topic. Option B describes scheduling, not a capacity calculation. Option C describes recruiting strategy, a related but distinct decision.

4. Why does the chapter say ratios looser than 3:1, such as eight students per mentor, tend to fail students?

  1. Because a mentor stretched across many students spends most of the session triaging who needs help most urgently, leaving little time for patient, question-first coaching
  2. Because state regulations cap coding clubs at exactly 3:1
  3. Because looser ratios always cost more in liability insurance
  4. Because students at looser ratios are statistically more likely to quit within a month
Show Answer

The correct answer is A. The chapter explains that at looser ratios a mentor manages only a minute or two of real attention per student per hour, spending most of the time triaging rather than coaching. Option B invents a regulatory cap the chapter never mentions. Option C fabricates an insurance-cost claim not discussed. Option D makes an unsupported statistical claim the chapter does not present.

5. Why does the chapter warn that a roster of twelve mentors doesn't guarantee twelve mentors at any given session?

  1. Because mentor availability tracking may show only some of those mentors typically attend, so real capacity should be planned against who actually shows up, not the full roster
  2. Because a roster automatically expires after six months
  3. Because only professional mentors are counted toward the official roster
  4. Because peer mentors are never included on the roster count
Show Answer

The correct answer is A. The chapter's warning is explicit: if availability tracking shows only seven of twelve mentors typically attend, real capacity is seven mentors times three, not twelve times three. Option B invents a roster expiration rule not in the text. Option C fabricates a restriction on which mentor types count toward the roster. Option D similarly invents an exclusion rule the chapter never states.

6. What risk does the chapter identify with sibling pairing that mixed age grouping does not necessarily share?

  1. Sibling pairing requires a separate parental consent form that mixed age grouping does not
  2. Sibling pairing always violates the child safety policy's two-adult rule
  3. A more skilled sibling can end up doing the other's work rather than coaching them through it, unlike a well-matched mixed-age pair
  4. Sibling pairing is only allowed for returning students, never for new students
Show Answer

The correct answer is C. The chapter notes sibling pairing can backfire if one sibling is consistently more skilled and does the other's work, whereas mixed age grouping works well when the older student is developmentally ready to help rather than dominate. Option A invents a separate consent-form requirement not discussed. Option B misapplies the two-adult rule, which concerns adult supervision, not student pairing. Option D fabricates a new-student restriction the chapter never states.

7. A club has nine active mentors. Using the chapter's 3:1 ratio, how many students can it responsibly serve?

  1. Nine students
  2. Eighteen students
  3. Thirty-six students
  4. Twenty-seven students
Show Answer

The correct answer is D. The chapter's own example states a club with nine active mentors can serve up to twenty-seven students at a 3:1 ratio, since each mentor is responsible for three students. Option A confuses the mentor count with the student capacity. Option B applies a 2:1 ratio instead of the recommended 3:1. Option C applies a 4:1 ratio, looser than the chapter's target.

8. A club only starts recruiting new mentors after it is already over-enrolled, and spends several weeks running well above 3:1 while background checks process. What does the chapter say the club should have done differently?

  1. Practiced adding mentors ahead of demand, since recruiting and background-checking new volunteers takes time and reacting after over-enrollment leaves the club running above ratio for weeks
  2. Waited even longer before recruiting, since demand often resolves itself
  3. Skipped background checks temporarily to add mentors faster
  4. Closed enrollment permanently rather than recruiting more mentors
Show Answer

The correct answer is A. The chapter states that adding mentors should happen ahead of demand, not in reaction to it, since a club that waits until over-enrolled will run above 3:1 for weeks while checks process. Option B contradicts the chapter's explicit recommendation to recruit proactively. Option C violates the non-negotiable background check requirement from Chapter 3. Option D is a more drastic step than the chapter recommends, which favors proactive recruiting over closing enrollment.

9. A club deliberately seats a first-time student next to a student who has attended for six months, so the newcomer has an immediate peer connection rather than facing a room of strangers alone. Which concept does this decision illustrate?

  1. Waiting list management
  2. Mentor skill matching
  3. New student placement
  4. Student to mentor ratio
Show Answer

The correct answer is C. The chapter defines new student placement as the deliberate decision of where a first-time student sits, ideally paired with a returning student for their first session for an immediate peer connection. Option A describes tracking families waiting for an opening, unrelated to seating decisions. Option B describes matching a mentor's strengths to a station, a different pairing decision. Option D describes the supervision ratio, not a seating placement choice.

10. A mentor notices that in a sibling pair, the older sibling has been quietly finishing the younger sibling's coding steps for her rather than letting her attempt them herself. According to the chapter, what standard should the mentor apply?

  1. Separate the siblings permanently and never allow sibling pairing again
  2. Apply the same "ask questions, don't take over" standard used for any peer-learning pairing
  3. Ignore it, since sibling pairing is exempt from peer-learning standards
  4. Ask the parent to sit in on every future session to supervise the pair directly
Show Answer

The correct answer is B. The chapter states a mentor watching a sibling pair should apply the same "ask questions, don't take over" standard as any peer-learning pairing, rather than letting a more skilled sibling simply do the work. Option A is a more extreme response than the chapter recommends, which favors coaching over separation. Option C directly contradicts the chapter's statement that the same standard applies. Option D invents a parent-supervision requirement not discussed in the chapter.
