How should a substitute teacher handle permission slips when the regular teacher is out before a trip?
A trip can land in a week when the regular teacher is sick or on leave. Here is how to hand off consent collection so nothing gets lost, whether you are the sub or the teacher planning ahead.

What the sub needs on day one
A substitute walking in cold cannot collect consent well. They need four things in the sub folder: the trip details (date, destination, departure time), the current list of who has and has not returned a form, blank copies of the form or the digital link, and the name of the office contact who owns the trip in the teacher's absence. If those four are present, a competent sub can keep the process moving. If they are missing, forms will pile up in a drawer until the teacher returns, and the deadline will not wait.

The status list matters most. A sub who does not know who is outstanding cannot remind anyone, and will end up re-asking families who already responded. If the teacher tracks returns on a roster, a photocopy in the folder works. If the school uses a digital system, giving the sub or the office view access to that trip takes a minute and means the list is always current without anyone copying it.

The sub's job: collect, record, escalate, and do not improvise
For the sub, the routine is simple. Collect any forms students bring in, note the date and the student's name on the roster the same day, and put the forms in one labeled folder that goes to the office at the end of the week or when the teacher returns, whichever comes first. Do not accept forms without a signature, do not fill in anything on a parent's behalf, and do not accept verbal messages from students as consent.
The sub should also not make policy decisions. If a parent calls with a custody question, a medical concern, or a request for an exception, the sub takes a message and hands it to the office contact. If a student's form arrives with a question written on it, same thing. A sub's authority is to keep the collection tidy and current, not to decide who goes on the trip.

Planning ahead when you know you will be out
A teacher who knows a leave is coming, for a surgery or a family event, should move the trip's consent deadline earlier if at all possible, so it closes before the absence. If that is not possible, name a co-teacher or the office manager as the trip owner in writing, transfer the status list to them, and tell families in the trip communication who to contact while you are out. Parents will otherwise send messages to a mailbox nobody is checking.
If chaperones were coordinated by the absent teacher, make sure their assignments and contact details are in the handoff too. A trip rarely fails because forms went uncollected; it fails because a chaperone quietly dropped out and nobody noticed. The handoff document should let the trip owner run the day without the original teacher, including the medical notes and the group lists.

When the teacher returns
The returning teacher's first task is to reconcile: the sub's folder against the roster, and the roster against any digital record. Expect a few forms without a recorded date, and a few students marked returned whose forms cannot be found. Sort it out that day, not the day before the trip. Then contact the remaining outstanding families directly, since they may have received a reminder from nobody during the absence.
Afterward, fix whatever broke. If the sub could not find the status list, put it in the sub folder permanently. If forms got separated from the roster, keep them together. If the digital record and the paper folder disagreed, decide which is the source of truth and use only that. The goal is a process that survives a week without its owner, because at some point every teacher is out during a trip week.

- The sub folder needs the trip details, the current outstanding list, blank forms or the link, and an office contact.
- A sub collects, records the same day, and escalates questions; a sub does not decide exceptions.
- A teacher with a planned absence should close the deadline early or name a written trip owner and tell families.
- On return, reconcile the folder against the roster immediately and contact outstanding families directly.
