# Substitute Lesson Plan

A substitute lesson plan is a day plan written for someone who has
never taught this specific class before: no knowledge of the room's
routines, the students' names or needs, or the classroom-management
systems already in place. It has to carry information an ordinary
[[lesson-plan]] can safely leave implicit, because the regular teacher
who'd use that plan already holds all of it in their head.

## Key components

- **Self-contained instructions** — activities explained step by step,
  assuming no prior knowledge of the class's usual shorthand or
  routines, with nothing left implicit.
- **Classroom procedures, spelled out** — how the attention signal
  works, how materials get distributed and collected, what the
  bathroom and transition procedures are, written down rather than
  assumed known.
- **Student-specific notes** — names and any information a substitute
  genuinely needs in the moment (a student who needs to sit near the
  front, a known allergy, a student who serves as a reliable helper),
  kept to what's actually necessary and appropriate to share.
- **Backup activity** — extra material for if the planned lesson runs
  short, since a substitute has no bank of on-the-fly filler content
  to fall back on the way the regular teacher does.
- **Emergency contacts and procedures** — who to call for help, where
  the office and nearest colleague are, and what to do for a fire
  drill or other disruption during the day.
- **A clear return-state expectation** — what the regular teacher
  needs back from the day: attendance, any notes on how it went, and
  any collected student work.

## Writing for someone with zero shared context

The single biggest failure mode of a substitute plan is written the
way the regular teacher would write a plan for themselves: full of
implicit shorthand ("do the usual warm-up," "collect like normal")
that means nothing to someone who has never been in the room. Every
instruction has to be checked against the question "would this make
sense to someone who has never met these students or seen this room
before?" — and if the answer is no, it needs to be spelled out. This is
also why classroom-management information matters as much as content:
a substitute who doesn't know the established attention signal or
transition routine will lose the room regardless of how good the
lesson content is, so those procedures need to be handed over
explicitly rather than assumed to transfer on their own.

## Common pitfalls

- **Assumed shorthand** — referencing "the usual routine" without
  spelling out what it actually is leaves a substitute guessing at
  exactly the moments where guessing causes the most disruption.
- **No buffer content** — a plan sized exactly to the period with
  nothing held in reserve leaves a substitute with unstructured time
  and no fallback if the lesson runs short.
- **Missing classroom-management details** — leaving out the attention
  signal, transition procedures, or behavior expectations treats
  content as the only thing that matters, when management routines are
  often what a substitute actually needs most.
- **Too little context on individual students** — omitting anything a
  substitute genuinely needs to know in the moment risks a
  preventable problem; but oversharing sensitive student information
  beyond what's necessary is its own separate problem to avoid.
- **No emergency procedures** — leaving out who to contact and what to
  do for a drill or incident puts a substitute in a bad position at
  exactly the worst time to be improvising.
