The Problem This Solves

When a formal complaint reaches a head of school, the investigation that follows is often improvised, under-documented, and legally fragile.

Most heads of school have never been trained in workplace investigations. They learned how to handle conflict, how to coach, how to give feedback, and then one day a written complaint arrives, often involving harassment, discrimination, or serious professional misconduct, and the head is expected to investigate competently within twenty-four hours of opening the email. The default approach is to talk to people informally, take notes in a notebook, and resolve the situation quietly. That approach works until it does not, and when it does not, the cost is significant.

A poorly run investigation harms everyone. The complainant feels unheard, the respondent feels ambushed, the institution becomes legally exposed, and the leader making the decision is operating without the documentation that protects their judgment. The gap is not in the leader's ethics. It is in the procedural infrastructure that makes good ethical judgment defensible.

This toolkit provides the procedural infrastructure. Investigation procedures, documentation templates, interview protocols, and finding letters, all calibrated for a Montessori school context but built to the standard a labor attorney would expect. It is for the schools that want to do this right when they do it, and that recognize the moment of need is not the moment to start building the process.

What’s Included

A complete investigations infrastructure, intake through finding.

Eight components covering the full arc of a formal workplace investigation. Built so a head of school or HR lead can run a defensible process without first having to learn investigations as a discipline.

Investigation Procedure Document

The formal procedural document that governs how investigations run at the school. Specifies the steps, the timeline, the standard of evidence, and the rights of all parties. Adoptable as policy by the board, which is the appropriate level of approval for this kind of document.

Intake and Triage Protocol

The structured process for receiving a complaint, determining whether a formal investigation is warranted, and deciding the appropriate scope. Reduces the most common error, which is either over-escalating routine concerns or under-escalating serious ones.

Interview Protocols

Working interview protocols for the complainant, the respondent, and witnesses. Specifies the questions to ask, the questions to avoid, the documentation to maintain, and the rights to communicate at the start of each interview. Built to produce useful evidence without compromising the integrity of the process.

Documentation Templates

A working set of templates for every document the investigation produces. Interview notes, evidence logs, timeline summaries, and the working file that holds the investigation together. Built so the documentation produces a defensible record without consuming the investigator's entire calendar.

Finding Letters

Pre-drafted finding letter templates for the three common outcomes, substantiated, partially substantiated, and not substantiated. Each template names what the investigation concluded, what the evidence supports, and what the institutional response will be. Calibrated to communicate clearly without exposing the school to additional risk.

Confidentiality and Communication Protocols

Specifies who needs to know what during the investigation, who does not, and how to manage the most common failure point, which is information leakage that compromises the integrity of the process and the dignity of the people involved.

Outside Counsel Engagement Guide

A working guide for when to involve outside counsel, what to ask them to do, and how to maintain leadership decision-making authority while engaging legal expertise. Reduces both the over-reliance on counsel that drains resources and the under-reliance that creates exposure.

Post-Investigation Implementation Tool

The structure for what happens after the finding letter goes out. Disciplinary action, restorative work, training requirements, and the follow-up that ensures the institutional response is real rather than symbolic.

Who It’s For

Schools that need to do this right when they do it at all.

The toolkit is for schools that recognize formal investigations as an infrequent but high-stakes responsibility, and that want to be ready before they are needed. It is not for schools running investigations weekly, it is for schools that want to handle the next one with full procedural integrity.

Heads of school who have never run a formal investigation and want infrastructure before they need it
HR leads building or refreshing the formal complaint process at the school
Boards expecting documented investigation procedures as part of governance
Schools that have recently mishandled an investigation and need infrastructure to do better next time
Schools entering accreditation cycles that require formal complaint procedures
Public charter Montessori schools whose authorizers require workplace investigation infrastructure
Heads of school inheriting an open complaint without a working procedural framework

How to Use It

Adopt the Investigation Procedure Document as formal policy through the board before you need it. This is the foundational step, and the timing matters, adopting the procedure during an active investigation creates the appearance of policy being made to fit the situation. Convene the leadership team and any HR support to walk the toolkit in advance, identify who plays which role in the most likely investigation scenarios, and adapt the templates to the school's voice and signature lines.

Pair with the Performance Concerns and Separation Toolkit, which addresses the related but distinct work of formal performance management. Investigations and performance management overlap, but the procedural standards are different. Most schools benefit from holding both toolkits in parallel.
