  "summary": "See how many absences or arrivals your classroom can absorb before violating ratio.",
  "description": "Ratio compliance is checked in real time, not on a monthly average, so the number that matters day-to-day is how much slack you have right now. This calculator takes currently enrolled children physically present, staff physically present, and the required ratio to compute your compliance buffer — how many more children could arrive, or how many staff could call out, before you're out of compliance. It's built for the front-desk or director moment of 'can I take this drop-in child' or 'can I let this teacher leave early,' not for long-range budgeting. A buffer of zero doesn't mean you're doing something wrong; it means you're staffed exactly to today's headcount and any change requires action (float staff, closing a spot, or turning away a walk-in) before it happens, not after.",
  "formula": "Max children allowed = staff present × ratio; buffer = max children allowed − children present; staff needed if one more child arrives = CEILING((children present + 1) ÷ ratio).",

  "faq": [
    {
      "q": "Is this a substitute for state licensing rules?",
      "a": "No. This is a quick operational math check using whatever ratio you enter; it does not know your state's actual licensing requirement, group-size caps, or mixed-age-group rules. Always confirm the exact ratio and any group-size maximum with your state licensing agency, since some states apply both a ratio and a separate absolute group-size cap."
    },
    {
      "q": "Why would 'buffer' show as negative?",
      "a": "A negative buffer means you're currently out of compliance with the ratio entered — more children present than your staff count supports. That needs immediate action: pull a floating staff member into the room, move children to another compliant classroom, or stop accepting walk-ins until staffing is corrected."
    },
    {
      "q": "Should front-line staff use this or is it a director-only tool?",
      "a": "It's built to be fast enough for a front-desk person to check before accepting a drop-in or a late enrollment, or for a lead teacher deciding whether a co-teacher can step out for a break. Real-time ratio awareness at the classroom level, not just at the director level, is what actually prevents violations."
    },
    {
      "q": "Does this account for children with additional support needs?",
      "a": "No. Some states adjust ratio requirements when a classroom includes children with an IEP or documented additional support need — that adjustment must be applied manually by changing the ratio input to reflect your specific classroom's approved ratio before relying on this calculator's output."
