sudden departure

Northfield High School principal out after investigation into student discipline

The principal of Denver’s Northfield High School resigned Tuesday rather than face being fired after a school district investigation found “multiple” instances of inappropriate responses involving the discipline of students at the school that opened this fall, Denver Public Schools officials announced Tuesday night.

Avi Tropper was hired with great fanfare to lead a bold new experiment at DPS’s first new comprehensive high school in 35 years. The goal: to build an integrated school and show that all students, regardless of past academic history, can succeed under the demanding International Baccalaureate program usually reserved for the highest achievers.

The district’s investigation found “multiple incidents” of problems with how students are disciplined, including inappropriate use of force, inappropriate escalation of relatively minor incidents, inappropriate supervision of security personnel, Tropper stating his intentions to use suspension as a tool to force at least one student out of the school and inappropriate behavior towards parents raising concerns, according to district staff and a letter to the Northfield community.

In an interview Tuesday with Chalkbeat, Tropper, who had been put on administrative leave during the investigation, said he did nothing wrong in the student discipline cases. He described the district’s investigation as “tremendously flawed,” featuring “falsehoods and lies.” He said the district failed to talk to faculty who could refute some of the claims.

Tropper said he resigned because he does not believe the district buys into the Northfield vision. He suggested district officials are bowing to pressure from a vocal group of Stapleton neighborhood parents who dislike the inclusive nature of the school and want their children in higher-level classes separate from others.

“We need a district that abides by its publicly stated values instead of folding under pressure,” Tropper said.

Susana Cordova, DPS’s chief of schools, said that was not true, and that the district stands by the investigation and its results.

“We remain 100 percent committed to the vision of Northfield High High School, which is a vision about an inclusive, high-performing school,” Cordova said. “This is not an easy decision to make. However, we believe that it was in the best interest of the school community to make this change based on the result of the investigation.”

DPS did not provide details of the discipline cases, but in a letter to families earlier this month noted that two families raised concerns about how their children were disciplined by a campus security officer. Both the officer and Tropper were put on leave during the investigation.

9News has previously reported that one of the incidents was triggered by a dress code violation, quoting the student’s mother as saying the school security guard “inappropriately handled” her daughter, holding her hands behind her back. She had been wearing a bandana.

Northfield opened in August with a freshman class and will add a grade every year.

Tropper refuted several of the findings of the district’s investigation. For instance, he said the claim that he was using suspension to force a student out is a “blatant lie.” He said the student was suspended for fighting, and his grandmother said she was planning to transfer him to another school. He said suspension is a last resort and the decision for a student to leave is up to the family, not the school.

Cordova said principals must enforce clear, consistent and fair procedures around behavior and discipline with the goal of keeping kids safe. In the letter to the school community, the district said it found multiple instances of cases not being dealt with promptly or fairly in accordance with districtwide discipline expectations and in a way that de-escalates conflict as effectively as possible.

Cordova said Tropper resigned in lieu of being fired.

Tropper wrote in his three-sentence resignation, which he let Chalkbeat review: “Please be aware that this resignation does not waive any legal right that I may have.”

Staff defections have accompanied the turmoil. A full-time teacher, two part-time teachers and an office staff member have left Northfield recently, district officials said. One teacher sent an email to school families just before resigning, saying she is “concerned that the administration is not addressing incidences of violence or threats of violence, which is causing bullying to escalate in the classroom.”

Tropper convened a staff meeting following the email, and a majority of staff did not believe that was an accurate depiction of the culture at Northfield, according to the earlier letter sent from district staff to families.

Tropper has plenty of support among remaining faculty who remain steadfastly loyal to him, and many parents.

Brent Stickrath, who left a job teaching in the IB program at George Washington High School in Denver to teach science at Northfield, said Tuesday he is disappointed Tropper is no longer leading the school.

Northfield stats
The school primarily draws from the following neighborhoods:
  • Green Valley Ranch
  • Montbello
  • East Park Hill
  • Stapleton

Student demographics

  • 29.4% Black
  • 30.7% Hispanic
  • 30% White
  • 8% multiple races
  • 2.8% Asian
  • .5% American Indian/Alaskan Native

Percent of students eligible for free and reduced-price meals

  • About 54%

“Northfield High is a safe place for our students to grow academically,” Stickrath said. “It just is. I think there is a mischaracterization that the school had a lot of discipline problems and so forth.  Really, the focus has been on academics. The focus will continue to be on academic growth and the development of strong citizens. I just think Avi was central to the vision of this school. I am just saddened he is not able to be a part of it anymore.”

Debra Jackson, who has a son at Northfield, also was disappointed to learn of Tropper’s departure.

“I just feel Avi really believes in the school, believes in the kids, and didn’t get a chance to follow through,” she said. “There are troubled students there, and not all will make it. But they should be given the opportunity to succeed.”

Other parents interviewed by Chalkbeat after school on Tuesday said the school has had a rough start, with too many students disrupting class and neither teachers nor administrators doing enough in response.

“It’s been chaotic,” said parent Carl Sakamaki, who described his daughter as a strong student who came up through Stapleton schools. “I don’t think they were ready. I think they’re trying, but a lot is falling short.”

Students interviewed Tuesday before the announcement of Tropper’s resignation painted a mixed picture of the school. A group of about half-dozen African-American freshmen said they felt stereotyped by staff, with one saying anyone male is perceived to be a gang member. But they also said the work at Northfield is challenging, teachers are mostly supportive and they’re learning.

“It’s been rough,” said freshman Earl Watkins. “It doesn’t feel like a real high school. They don’t treat us like we’re almost adults. Not all of us disrespect the adults.”

DPS said a former DPS principal, Ed Salem, will continue as acting principal and a new interim principal is expected to be named shortly for the remainder of the school year.

The school security officer’s status is not yet resolved, district officials said. He too was placed on administrative leave.

Chalkbeat deputy bureau chief Nic Garcia contributed information to this report.

Need classroom decor inspiration? These educators have got you covered.

This school year, students will spend about 1,000 hours in school —making their classrooms a huge part of their learning experience.

We’re recognizing educators who’ve poured on the pizazz to make students feel welcome. From a 9th-grade “forensics lab” decked out in caution tape to a classroom stage complete with lights to get first graders pumped about public speaking, these crafty teachers have gone above and beyond to create great spaces.

Got a classroom of your own to show off? Know someone that should be on this list? Let us know!

Jaclyn Flores, First Grade Dual Language, Rochester, New York
“Having a classroom that is bright, cheerful, organized and inviting allows my students to feel pride in their classroom as well as feel welcome. My students look forward to standing on the stage to share or sitting on special chairs to dive into their learning. This space is a safe place for my students and we take pride in what it has become.”

Jasmine, Pre-K, Las Vegas, Nevada
“My classroom environment helps my students because providing calming colors and a home-like space makes them feel more comfortable in the classroom and ready to learn as first-time students!”


Oneika Osborne, 10th Grade Reading, Miami Southridge Senior High School, Miami, Florida
“My classroom environment invites all of my students to constantly be in a state of celebration and self-empowerment at all points of the learning process. With inspirational quotes, culturally relevant images, and an explosion of color, my classroom sets the tone for the day every single day as soon as we walk in. It is one of optimism, power, and of course glitter.”

Kristen Poindexter, Kindergarten, Spring Mill Elementary School, Indianapolis, Indiana
“I try very hard to make my classroom a place where memorable experiences happen. I use songs, finger plays, movement, and interactive activities to help cement concepts in their minds. It makes my teacher heart so happy when past students walk by my classroom and start their sentence with, “Remember when we…?”. We recently transformed our classroom into a Mad Science Lab where we investigated more about our 5 Senses.”


Brittany, 9th Grade Biology, Dallas, Texas
“I love my classroom environment because I teach Biology, it’s easy to relate every topic back to Forensics and real-life investigations! Mystery always gets the students going!”


Ms. Heaton, First Grade, Westampton, New Jersey
“As an educator, it is my goal to create a classroom environment that is positive and welcoming for students. I wanted to create a learning environment where students feel comfortable and in return stimulates student learning. A classroom is a second home for students so I wanted to ensure that the space was bright, friendly, and organized for the students to be able to use each and every day.”

D’Essence Grant, 8th Grade ELA, KIPP Houston, Houston, Texas
“Intentionally decorating my classroom was my first act of showing my students I care about them. I pride myself on building relationships with my students and them knowing I care about them inside and outside of the classroom. Taking the time to make the classroom meaningful and creative as well building a safe place for our community helps establish an effective classroom setting.”


Jayme Wiertzema, Elementary Art, Worthington, Minnesota
“I’m looking forward to having a CLASSROOM this year. The past two years I have taught from a cart and this year my amazing school district allowed me to have a classroom in our school that is busting at the seams! I’m so excited to use my classroom environment to inspire creativity in my students, get to know them and learn from their amazing imaginations in art class!”


Melissa Vecchio, 4th Grade, Queens, New York
“Since so much of a student’s time is spent inside their classroom, the environment should be neat, organized, easy to move around in but most of all positive. I love to use a theme to reinforce great behavior. I always give the students a choice in helping to design bulletin boards and desk arrangements. When they are involved they take pride in the classroom, and enjoy being there.”

After Confederate flag dispute at Colorado football game, schools pledge to bring students together

Manual High students.

Acknowledging “we may never have a conclusive picture of what happened,” two Colorado school districts sought to move past a controversy over whether a Confederate flag was displayed at a football game and open a conversation between the two school communities.

The principal of Manual High, Nick Dawkins, wrote in a community letter over the weekend that the visiting Weld Central High School team “displayed a Confederate flag during the first quarter of the (Friday night) game, offending many members of the Manual community.”

Officials from Denver Public Schools and Weld County School District Re-3J released a joint letter Tuesday saying that based “on what we have learned to date, however, the Weld Central team did not display the Confederate flag.” At the same time, it said, multiple Manual eyewitnesses “reported seeing spectators who attempted to bring a Confederate flag into the game and clothing with flag images.”

Going forward, students from the two schools — one rural and one urban — will participate in a student leadership exchange that has student leaders visit each other’s schools and communities to “share ideas and perspectives,” the letter says.

“At a time in our country when so many are divided, we want our students instead to come together, share ideas and learn together,” says the letter, which is signed by the principals of both schools and the superintendents of both school districts.

The alleged incident took place at a time when issues of race, social injustice, politics and sports are colliding in the United States, making for tough conversations, including in classrooms.

Weld Central’s mascot is a Rebel. Manual, whose mascot is the Thunderbolts, is located in one of Denver’s historically African-American neighborhoods.

Dawkins in his initial community letter also said “the tension created by the flag led to conflict on and off the playing field,” and that three Manual players were injured, including one who went to the hospital with a leg injury. He also said some Manual players reported that Weld Central players “taunted them with racial slurs.”

Weld Central officials vehemently denied that their team displayed the flag. In addition, they said in their own community letter they had “no evidence at this point that any of our student athletes displayed racially motivated inappropriate behavior.”

They said district officials “do not condone any form of racism,” including the Confederate flag.

Weld Central fans told the Greeley Tribune that they didn’t see any Confederate flag.
