Description

Book Synopsis
School of Errors establishes another voice in the discussion of how to promote safe schools. It challenges the unchecked expansion of school fortification and questions the realized benefit of inter-agency collaboration during a sentinel event. This book offers an alternative to traumatizing simulations by providing clear options for improving school safety by the empirically-proven effective measures of leakage detection (preventive) and sensemaking (reactive). School of Errors restores the scientific method to school safety and clears a path through the media rhetoric fogging this vital topic.

Trade Review

School safety is a primary concern for any parent, teacher, or school administrator today. Perrodin (Viterbo Univ.) has extensive experience with and background in safety training, and he provides a realistic view of the topic, including practical ideas and solutions for school systems to implement. He cautions of "safety experts" who are more interested in making a profit than protecting schools, noting that administrators should be wary of proposed solutions that only advocate for more safety cameras, metal detectors, or other flashy technology. Instead the author asks for schools to consider "the torus," a way of visualizing familiar places, events, and daily routines and their interruptions as a possible solution, along with situational awareness. Perrodin cleverly uses a bagel to illustrate this point. He believes that schools must be ready to let go of the familiar and improvise, emphasizing a student-centered approach, particularly in the section on drill fidelity, stating that drills should be conducted less frequently but with more urgency to teach students skills to use in a particular situation rather than just to show them what could happen. This accessible book will appeal to multiple audiences and would be a valuable addition to any library. Summing Up: Recommended. All levels.

Dr. David Perrodin’s School of Errors allows readers inside the mind of an expert educator, a national resource in school safety research, and a compelling story teller. Perrodin lays out a guide for considering safety that prioritizes data-driven research over rhetoric, student learning over unnecessary fear, and wisdom over bumper sticker solutions. At least one person on every school board should have read this book before weighing another district safety decision. This is essential reading for school leaders, but worth the time for anyone interested in the larger national dialogue around safety. His gift as a writer is to connect the particulars of school safety to the larger realities of human existence, history, and patterns that only a gifted expert can show us. -- Seann Dikkers, author, “TeacherCraft, Mobile Media Learning, and Real-Time Research”
In every field there is that one man who is led by facts and truth rather than fads or group thinking. When it comes to school safety, David Perrodin is that man, and his book School of Errors reveals why. -- TJ Martinell, Lens award-winning reporter and writer at the Tenth Amendment Center
A brave demonstration of speaking truth to power “School of Errors” rips the lid off the billion-dollar school safety industry. Using real-world examples of successful responses in desperate situations, David contrasts the expensive window dressings pitched to panicked parents, with the inexpensive and effective approaches proven to actually work. Read this book before you let your school waste another precious dollar on meaningless safety ‘theater.’ -- James B. Sibley, Esq., Special Education Attorney, Tollner Law Offices
Over the last 20 years, in the wake of unthinkable school shootings, school safety has propelled itself to priority number one for school leaders. A priority that has not had the thoughtful support of understanding what we need to do to address the simple question, “What if?” A question with an endless number of scenarios which we honestly struggle to reasonably counter. We spend countless amounts of resources of time and money to fortify our schools and train our staff. Yet intuitively we sense we are somehow possibly missing the boat. David allows us a moment to step back and thoughtfully reconsider the landscape before us. -- Mati Palm-Leis, superintendent, School District of Mellen Wisconsin
Dr. David Perrodin gives the reader a contrarian view on the current school security establishment. The emphasis is placed more on the individual for timely action than it does bollard fencing. Perrodin’s School of Errors puts you in the front row of active shooter crime scenes. What is needed and how to survive them. -- Thomas Marchetti, retired Los Angeles Police Detective
If you have any interest in saving kids’ lives, you need this book. It’s not a regurgitation of the “hide-run-fight” mantra, but a deeper study of what humans do in chaotic, unpredictable emergencies, and how to apply those lessons. We say that, 'An ounce of prevention is worth a pound of cure.' In real life that means it is cheaper, easier, and more effective to spot troubled students than to spend millions on "security bling” that we already know doesn’t work. Better to cultivate a principles-based flexible attitude than memorize a dozen rigid, impossibly specific responses that only work in the unlikely event that your chaos matches a previous chaos. David Perrodin gives you a way to think about the problem and an insight into how the humans you deal with are probably going to handle it anyway, so you can work with nature instead of trying to script the unpredictable. -- Rory Miller, author, “Meditations on Violence”
Rather than throwing hockey pucks at a school intruder read David Perrodin’s important book and learn what both common sense and law enforcement experts suggest you do to protect your students. -- David Obst, Pulitzer Prize winning educator; author, "Too Good to Be Forgotten: Changing America in the ’60s and ’70s"
Dr. Perrodin boldly reveals the internal mechanisms of the billion dollar school safety industry in his must-read book School of Errors. As a school district administrator in elementary education, the safety of my students and staff is a matter of the utmost importance. David untangles the issues all school leaders face from years of vague policy guidance, unchecked fortification and a complete absence of accessible design for safety instruction and threat reporting systems. Students have been pushed to the sidelines of safety. School of Errors is the overdue invitation to America's youth that they are crucially needed to inform the practices and systems that promote the safety of their school environment. This book will immediately change how you think about school safety! -- Missy Herek, Elementary Principal, Hillsboro School District, Hillsboro, Wisconsin
David Perrodin adeptly tackles and untangles a topic that is on everyone’s minds these days – keeping schools safe -- with blunt honesty and keen insight drawn from years of experience. The book debunks the many “quick fix” solutions that do nothing but drain taxpayer dollars in exchange for a facile illusion of safety. Dr. Perrodin’s goal is to instead urge all involved to look at the problem from a sober, realistic viewpoint and pursue safety strategies that emphasize flexibility, common sense and the ability to assess how things actually work in the real world. There is no other book like it available today, making it a must read for both parents and experts alike. -- Mike Valentino, editor, "Jersey Joe Walcott: A Boxing Biography"
Dr. Perrodin’s book guides us back to true prevention. Millions of dollars are being spent on fortifying our schools, when possibly the assailant might already be behind the walls. School Safety should be focused on mental health services, reporting tools, improving school climate, and threat assessment training. -- Salvador Arias, safe schools coordinator, Kern County, California
School safety has been an enigma to school officials and parents alike. Misguided solutions presented by the mainstream media have provoked us into implementing knee-jerk practices in response to school tragedies. Dr. David Perrodin’s book provides a steadfast approach, removing the rhetoric while providing clear focused guidance on understanding school safety and the tools needed to implement guided adaptive critical thinking during chaotic emergency situations. School Officials, as well as parents, would benefit greatly from reading this book. -- Hector Solis, creator and host, Awareness Podcast
In School of Errors, David Perrodin offers comprehensive, practical expertise around school safety. Following some bullying complaints and behavior incidents a few years ago, we hired David as a consultant during a review of District safety operational systems. Under his advisement, and vetted through research and his own field experiences, our district revamped its procedures. Based on student-centered needs, the evidence-based practices (emphasizing prevention, restoration, and accountability) were so relevant that our district continues to use them today. With adverse social and mental health issues on the rise in our country, school personnel will find David’s message to be just the right antidote. Read his book and start the work! Time is critical and our children deserve nothing less. -- Cynthia Russell Smith, director, Student Services, Marinette School District, Marinette, Wisconsin
School district administrators face an uphill battle when it comes to ensuring safe schools for their students, staff and families. School of Errors gives schools a road map for navigating the gauntlet of challenges around school safety. Dr. David Perrodin delivers research-tested, relevant strategies for creating and sustaining safe schools. -- Joe Bruzzese, CEO, Sprigeo
At a time when public awareness of school safety is at an all time high, Dr. David Perrodin’s School of Errors, provides practical, evidence-based wisdom. School administrators will be well-served to peruse these pages before giving into pressure to purchasing costly safety equipment or developing complex safety procedures. -- Michele Butler, principal, Arcadia Middle School, Arcadia, WI
As a parent of two children with special needs, I often have specific questions about school safety. What are my children being taught about safety? What do they actually understand about safety and reporting threats? How does the safety plan work when somebody is absent? Administrators assure parents that schools are safe. Yet we know from our own experiences that during a crisis, something will happen and scripted plans will be hurled out the window. Then what? Dr. Perrodin gives us the expert insight of someone who can answer that question. I highly recommend you read School of Errors and really let it all sink in. -- Tabatha Malliard, parent of two children with special needs, Pennsylvania
