Substitute Teacher in My Room Today

Quick guidance, fidelity, communication, and how to keep the day on track

For paraprofessionals working alongside substitute teachers

Why this brief

Substitute days are some of the most variable in the school year. Some subs are seasoned veterans who know your students; some are new graduates filling in for the first time; some are warm bodies hired through an agency to cover the day. Sub days can go beautifully — students engage, lessons happen, the day flows — or terribly: students dysregulate, fidelity collapses, mistakes ripple into next week. The difference is often whether the para and sub coordinate effectively, the para has done the prep work, and the team has built systems for sub days.

This brief covers the practical version: how to brief a sub at the start of the day, how to support without overstepping, how to manage your students' specific needs when their main teacher is out, and what to do when sub days go sideways. Brief 16.04 (When the Para Is Out) covers the reverse situation; this one is when the teacher is out and the sub is in.

| :-: |

| The frameSubstitute teachers are professionals doing a hard job under hard conditions. Many are walking into rooms they don't know, with students they don't know, expected to deliver lessons designed by someone else. Your job as the para is to be the continuity that makes their day workable and ensures your students don't lose ground. Done well, sub days can be productive and even pleasant; done badly, they can derail a week. |

Who this brief is for

Paras whose supervising teacher is out

Paras working in classrooms with frequent substitute coverage

Paras supporting students whose IEPs or BIPs require specific implementation

Paras new to handling sub days

Supervising teachers and admins building sub-day systems

Before sub days happen

Most sub-day issues trace to lack of preparation. The work happens before the sub arrives, ideally weeks in advance — though some subs are last-minute.

Sub binder or folder

Most well-organized classrooms have a sub folder. If yours doesn't, build one with the supervising teacher's input. It typically includes:

Daily schedule

Class roster with relevant notes

Building map and key locations (bathrooms, nurse, office)

Emergency procedures

Specific student information (per the student's plan and confidentiality)

Behavior expectations and key strategies

Names of supporting staff (paras, related-service providers, admin)

Emergency contact information for admin, nurse, security

Specific to your students

Brief profile of each student you support, anonymized as appropriate

Triggers and helpful strategies

Specific accommodations the sub should provide

How the student communicates

Any medical considerations

Brief 13.01 (FERPA) — confidential information should be in the sub binder under appropriate handling

Lesson plans

Subs typically receive lesson plans from the teacher

Plans should be detailed enough to follow without prior context

Backup activities for if plans don't work

If you know the sub is coming

Pre-meet briefly if possible — even 5 minutes helps enormously

Walk through the day

Highlight key student information

Identify what you'll handle vs. what the sub handles

If it's a surprise

Most sub days come with little notice

Have your prep work ready in advance so you can brief the sub on arrival

Don't expect to do briefings while also supporting students

The morning briefing

Brief the sub. Don't assume they know anything. Specifically:

First few minutes

Welcome them — they're often anxious about the day

Walk through the schedule briefly

Show them where things are (sub folder, materials, your station)

Point out other staff in the room (other paras, related-service providers expected)

Key student information

"This is Marcus — he uses an AAC device, brief instructions only, look for his thumbs-up signal that he's ready"

"Maya can't be on the same side of the room as Jasmine — there's a history"

"Aiden has a BIP; if he starts to escalate, the plan is X"

"Lisa needs sensory breaks every 30 minutes — I'll handle them"

Specific to students with significant disabilities, IEP requirements, or behavior considerations

Practical logistics

Bathroom procedure — when, who needs supervision, where the closest accessible bathroom is

Lunch — your role, sub's role, transitions

Specials / specials transitions

End-of-day routine

Bus or pickup procedures

Emergency information

How to call admin or nurse

Emergency procedures (fire, lockdown — brief 16.08)

Specific medical situations (allergies, seizures, etc.)

First aid supplies and nurse

What you'll handle vs. what they'll handle

Establish division clearly: "You teach the lesson; I'll handle behavior support and individual accommodations"

Don't volunteer for everything — manage your own role

Don't usurp their teaching role — let them teach

Tone

Friendly and professional

Don't intimidate or condescend

They're often more nervous than you might think

They're more likely to be effective if they feel respected

During the day

Support without taking over

This is the central skill of sub days. The sub is the teacher today; you're support. But also, you know things they don't, and you're the continuity. Balancing these is the work.

Stay in your lane — handle what you'd normally handle

Don't run the lesson yourself

Quietly fill in gaps as needed

Reinforce the sub's authority with students

Address sub-driven errors gently and privately when possible

If the sub is struggling

Step closer — your physical presence stabilizes the room

Quietly suggest specific moves: "You might try X here"

Take on more of the behavior support if the lesson is unraveling

Don't take over the teaching unless safety requires

Notify admin if the sub is genuinely failing — this happens

Maintain your students' programs

Implement IEP accommodations even if the sub isn't

Run BIPs as written

Take data as usual

Keep the structure your students depend on

Watch for student stress about the change

Some students dysregulate when their teacher is out

Routine + your steady presence helps

Pre-warning when possible (brief 11.04 Routines and Transitions covers this)

Visual schedule reference

Brief check-ins with affected students throughout the day

Don't over-explain

Don't constantly correct the sub in front of students

Don't talk over them

Don't roll your eyes or signal disrespect

Save substantive feedback for end of day or admin

Quiet redirection

If the sub asks a student to do something that conflicts with the IEP, redirect quietly

"Mrs. Lee, we usually do this for Marcus — could I take this part?"

Often a quick handoff resolves the issue

Student dynamics on sub days

Students react differently to subs. Some thrive; some struggle. Awareness helps.

Common patterns

Some students push limits with new adults — testing what's allowed

Some students dysregulate due to broken routine

Some students enjoy the change and engage well

Some students miss their teacher and grieve briefly

All of these are normal

Specific to students with disabilities

Students with autism often particularly affected by routine disruption

Students with anxiety may worry

Students with attachment issues may have stronger reactions

Students with regulation challenges may have harder time

Brief 11.04 (Routines and Transitions) covers the broader frame

What helps

Pre-warning when possible — "Tomorrow Mrs. Patel will be out; Mr. Lee will be subbing"

Visual schedule referencing the sub day

Maintaining routines as much as possible — same morning meeting structure, same workflow

Your steady presence — students often look to you for cues

Brief acknowledgment of feelings: "It's a different day with Mr. Lee here. We'll have a great day"

Behavior expectations

Same expectations as usual

Don't lower the bar because it's a sub day

Don't raise the bar because the sub doesn't know the kids

Consistent enforcement of class norms

Maintaining fidelity

One of the biggest costs of sub days is loss of fidelity — programs not run as designed, accommodations skipped, BIPs not implemented. Your role is keeping fidelity for the students you support.

IEP services

Services in the IEP must be provided

If the sub doesn't know about them, you implement

Document — was the service provided?

Brief 02.01 (IDEA), 02.05 (IEPs)

BIP implementation

Antecedent strategies

Reinforcement schedule

Crisis response if needed

Brief 05.03 (Reading and Running a BIP)

Specific medical needs

Medications administered on schedule (per district policy and brief 09.04)

Glucose monitoring

Seizure protocols

Brief 09 series

AAC and communication systems

AAC device used throughout the day

Modeling continues

Brief 10.02 (AAC Overview)

Data

Continue your data collection

Note context — sub day — when relevant

Brief 06.01 (Data Types Overview)

If the sub interferes with fidelity

Address quietly in the moment when possible

Document specifically afterward

Brief admin or supervising teacher about gaps

Don't simply accept failure of fidelity as inevitable on sub days

Sub-para dynamics

How you and the sub relate matters. Some patterns:

Good dynamics

Mutual professional respect

Clear division of roles

Coordination throughout the day

Handling difficulties together

End-of-day handoff

Difficult dynamics

Sub who treats para as subordinate or unwelcome

Sub who undermines para's role with students

Sub who refuses to listen to information about students

Sub who is incompetent and won't accept help

Handling difficult dynamics

Stay professional — don't escalate in front of students

Quiet conversation if possible

Document patterns

Notify admin if sub is genuinely problematic

Brief 13.05 (When You See Something Wrong) covers escalation

If the sub is problematic for students

Inappropriate language or behavior toward students

Failure to maintain safety

Discrimination or harassment

Document immediately and notify admin

This warrants formal report

If you're a sub yourself

Some paras sub for absent paras or absent teachers

Brief 16.04 (When the Para Is Out) covers this from the other angle

Bring same professionalism, same humility about the unfamiliar room

Long-term substitutes

Sometimes the teacher is out for an extended period — illness, family leave, leave of absence. Long-term subs are different from one-day subs.

More like the regular teacher

Often state-certified or working toward it

Often paid more

Have more responsibility

Build relationships with students

Take on more of the planning

Para's role

Continuity for students

Support the long-term sub in learning the students and program

Help maintain fidelity of IEPs and BIPs

Bridge to the regular teacher when they return

Long-term sub challenges

Sub may have own approach that conflicts with regular teacher's

Students sometimes resist the change

Programs can drift in absence of regular teacher's design

Communicating with the absent teacher

Sometimes appropriate to maintain communication

Sometimes the absent teacher prefers complete separation

Defer to admin and the absent teacher's preference

Maintaining the program

Brief 16.04 (When the Para Is Out) — applies in reverse here

BIPs and IEPs continue

Push for stability and consistency

Document drift if it's happening

Sub quality issues

Sometimes subs aren't qualified for the room they're in. This is a structural problem; here's how to navigate.

Common quality issues

No special education background sub assigned to a self-contained classroom

Sub with no behavior management skills assigned to a behavior-intensive room

Sub who can't manage the basic logistics

Sub without language skills assigned to ELL-heavy classes

In the moment

Step up to bridge gaps

Don't take over the teacher role unless safety requires

Maintain your students' programs

Notify admin if the situation isn't workable

Pattern documentation

If sub quality is consistently poor in your school, that's a structural issue

Document specific instances

Bring patterns to admin and union

Brief 13.05 (When You See Something Wrong) covers escalation

Equity considerations

Specialized programs (SpEd, ELL) tend to get less-qualified subs nationally

This pattern is documented and warrants attention

Brief 15.01 (Disproportionality) covers related dynamics

Documentation

Sub days warrant some documentation.

End-of-day notes for the regular teacher

How the day went generally

Anything noteworthy — incidents, accomplishments, concerns

Where the sub left things vs. where they should be

Note in your daily log

If issues occurred

Specific documentation

Notify admin if warranted

Brief 13.05 covers escalation

Students' data

Maintain your data

Note 'sub day' in the data so the team can interpret patterns

If the sub failed to implement IEP services

Specific documentation

Notify case manager and admin

This is a FAPE issue; brief 02.01 covers

Confidentiality

Same FERPA rules apply

Don't post about sub days on social media

Don't gossip about specific subs

End of day pickup

Brief the sub on what worked

"Today went well — students did great with the math activity"

Affirms what they did right

Helps them grow as subs

Note for the regular teacher

Quick summary of the day

Specific incidents or notes

Where the sub left things

Any action items for the teacher's return

Materials and space

Help return materials and classroom to expected state

Specific items the regular teacher will need on return

Note any supplies that ran out or got moved

Sub feedback (if appropriate)

Some districts have sub feedback forms — fill out honestly

Praise good work

Note significant concerns through proper channels

Decompression

Sub days are often more tiring than regular days

Allow yourself recovery time

Brief 14.02 (Setting Boundaries) — don't keep working past contract because of sub-day complexity

Building team-level sub readiness

Some longer-term work to make sub days work better.

Sub binders

Build them with the supervising teacher

Update annually

Test by reviewing with someone unfamiliar with the room

Para-specific sub coverage

Brief 16.04 (When the Para Is Out) covers when YOU are the absent one

Some districts have specific paraprofessional substitutes; some don't

Subs covering paras face their own challenges

Frequent-sub planning

If your room has frequent subs, build more robust systems

Pre-printed visual schedules

Pre-prepared lesson backup activities

Standard intro letter for incoming subs

Sub culture

Some districts have strong sub-mentor cultures

Some have transient sub pools that turn over constantly

Build relationships with subs you see repeatedly

Welcome them; they're more likely to come back

Long-term equity push

Districts often invest more in sub training for some schools than others

Push for high-quality sub coverage for SpEd and high-need classrooms

Scenarios

Scenario 1: A surprise sub on a hard day

You arrive at school and learn the regular teacher is out unexpectedly. The sub is new and looks anxious.

Welcome them warmly. Walk through the schedule. Brief them on key student information — focus on what they need to know to manage the day, not everything. Identify what you'll handle (your students' specific needs, behavior support) vs. what they'll handle (the lesson, broad classroom management). Stay close throughout the day. Document anything noteworthy. End of day, give them a kind summary — they'll be more confident next time.

Scenario 2: A sub who won't accept input

The sub assigned today seems to think they don't need your help. They're dismissing your information about students.

Stay professional. Don't escalate in front of students. Quietly: "I'm just sharing what's worked for these students because their plans require specific things." If the sub continues to dismiss, focus on what you can do — implement IEPs and BIPs yourself, support your students' programs. Document the pattern. Notify admin or supervising teacher about the issue. Brief 13.05 (When You See Something Wrong) covers escalation.

Scenario 3: A behavior incident the sub is mishandling

Your student is escalating. The sub is responding poorly — raising voice, ultimatum, no de-escalation.

Step in to take over the behavior support, kindly. "Mrs. Lee, let me help with this — I know his plan." Implement the BIP. De-escalate per training. Don't argue with the sub in front of the student. Once resolved, brief the sub: "His plan is X; here's what works." Document. If the situation was unsafe, notify admin. Brief 05.10 (Escalation Cycle) and 05.11 (Crisis Response).

Scenario 4: A long-term sub who's drifting from the regular teacher's program

Six weeks into a long-term sub coverage, you notice the sub is doing things differently than the regular teacher — lessons, classroom management, even some IEP implementation.

Diplomatic but real. "I want to flag I've noticed some shifts. Here's what was happening before \[teacher\] left, just to keep things consistent for the students." If the sub doesn't adjust, bring it to admin. The regular teacher's program should continue during their absence to the extent possible. Document. Brief 16.04 (When the Para Is Out) covers fidelity issues from the other angle.

Scenario 5: A sub who is inappropriate

The sub is making sarcastic comments about students, including comments about their disabilities.

This is wrong on multiple levels. Address immediately if you can do so safely: "Mrs. Lee, can we talk over here for a sec? Those comments aren't appropriate." If they don't adjust, notify admin during the day. Document specifically. This may warrant a formal complaint and the sub being removed from rotation. Brief 13.05 (When You See Something Wrong) and 13.06 (Scope of Practice). Don't tolerate this — your students' dignity is at stake.

Scenario 6: A great sub day

The sub turned out to be excellent — engaged with students, ran the lessons well, asked good questions.

Tell them. "You did a great job today — the kids really responded to you." Tell admin. Some districts have ways to flag preferred subs. Strong subs are valuable; encouraging them to come back benefits future days. End-of-day handoff for the regular teacher should note: "Mrs. Lee was excellent — would be great to see her again."

Closing thought

Sub days are part of school life. Done well, they're days that move along, students learn, programs run with reasonable fidelity, and everyone goes home tired but okay. Done poorly, they're days students remember as chaos, programs lose ground, and the regular teacher returns to picked-up pieces.

As a para, you're often the continuity that makes the difference. The sub is teaching today, but you know the students, you carry the IEPs and BIPs, you maintain the relationships and routines that make the room functional. That role is real work. Brief well, support without overstepping, maintain fidelity for your students, document what matters, and recover after. Build sub-binders and systems before they're needed. The pattern of your sub-day work over time builds the kind of practical skill that makes you valuable to your team and students.

| Bottom lineBrief subs thoroughly at start of day. Stay in your lane while supporting. Maintain IEP and BIP fidelity. Address issues quietly when possible. Document significant issues. Treat subs professionally — they're often anxious. Build systems (sub binders) before they're needed. Notify admin if sub is genuinely failing or harming students. Allow recovery time. The continuity you provide is part of what makes the school work. |
