TSIS Accountability Project

A documented account of safeguarding failures at Tien Shan International School (TSIS) — an English-medium school in Almaty, Kazakhstan — focused on transparency, accountability, and the protection of students.

By Joe & Sharon Byerly — former teachers at Tien Shan International School


If you've found your way here, you probably have some connection to Tien Shan International School. You may be a parent, a student, an alumnus, or a teacher. Whoever you are, you are welcome here.

We are Joe and Sharon Byerly. We served at Tien Shan International School, most recently from 2023–2025. We worked directly with students in teaching, chaplaincy, and support roles. We left in January 2025.

We did not leave quietly, and we did not leave without reason.

We left after raising concerns about the handling of reported misconduct, the treatment of students, and the response of leadership to documented issues. Over time, it became clear that those concerns would not be addressed transparently within the system.

This publication exists for one reason: transparency.

Timeline of Events

A chronological account of what was reported, and what happened next.

Fall 2022
A student discloses ongoing emotional and physical abuse and neglect. Multiple staff verify the situation. The head of school responds: "Unless there are bruises, there's nothing we can do." The student remains in that situation.
August 2024
The school year begins. Joe and Sharon join a newly formed child safety team, incorporating training from TCKTraining.com into school safeguarding practices. Administration appears supportive.
August 29, 2024
First child safety meeting. Cecily Bader self-reports engaging in "a lot of" grooming behavior.* Both the Middle School principal/Child Safety Team lead and the High School principal are present. No immediate action or escalation follows.
September 2024
Another teacher reports concerns about Cecily.* An investigation begins.
September – December 2024
Seven students and three additional staff members come forward with independent, consistent, and corroborating accounts of concerning behavior.* The child safety response team compiles an eleven-page findings document and submits it to administration per school safeguarding procedures.
Late 2024
Administration alters the findings.* The letter to Cecily leads with affirmations of her contributions. Violations are presented in vague, incomplete terms with no defined accountability path. Board member Jonathan McDonald manipulates aspects of the child safety process and discredits the child safety team.*
Late 2024
Cecily's sending organization is informed and is ready to pull her from the field. Administration tells them the situation is "being handled."*
Late 2024
Cecily denies the concerns, suggesting others are "jealous of her relationships with students." Additional students disclose that Cecily discussed her personal struggles with pornography in co-ed classroom settings — Class of 2025 (11th grade health) and Class of 2027 (8th grade health).* Parents were never informed. The child safety team's proposal to communicate with families is blocked by administration.
Late 2024 – January 2025
Joe is told he is "trying to destroy the school." Students are told he is "delusional."* Sharon is pressured to doubt Joe's experience.* Staff describe having "given up fighting" leadership. The Byerlys are labeled "woke" for listening to students.
January 2025
Joe and Sharon leave Tien Shan International School.
February 2026
Campus Crusade for Christ (CRU) and the International Mission Board (IMB) are placed on formal legal notice. Their responses are vague and do not engage substantively with what was shared.
April 2, 2026
The TSIS Accountability Project launches publicly.
April 14, 2026
Sharon sends a letter directly to approximately 50 members of the Tien Shan community — teachers, parents, and mission-connected individuals.
April 23, 2026
TSIS Director Christine Wicker sends an official email response to staff and parents. We publish the full text.
April 24, 2026
Part Five: When the Conversation Shifts — on how the conversation moved from pattern to particulars, and why the full picture still matters.
April 26, 2026
Part Six: When the Framework Is Applied — the school's own Mentoring vs. Grooming chart, placed next to the school's own documented reports.
April 29, 2026
Part Seven: Not a Safe Place — a young student on the basketball court, curled into himself, said quietly: “This school is not a safe place.”
May 1, 2026
Part Eight: When the Pattern is Clear — not a moment, not a misunderstanding. The question is no longer what happened. The question is what will be done in response.

We Were Not Silent

We kept speaking. We kept advocating. But trauma kept us from telling this story…until now.

We left Tien Shan International School in January 2025 after a teacher engaged in grooming behaviors, staff reports were suppressed, and the administration altered documented findings. This is why we left.

Why People Don't Speak Up

Fear, trauma, and the system that enforces silence.

Speaking up inside Tien Shan is costly — immediately. What happens to those who raise concerns, and why staff who witness harm stay quiet.

What the System Protects

Not students. Not staff. It protects itself.

TSIS operates like many institutions: its primary priority is its own survival. The pattern of dismissed prevention, missing safeguards, and closing ranks when leadership is challenged.

When the Conversation Shifts

From pattern to particulars — how a response can feel like engagement while quietly changing the question.

After concerns are raised publicly, the conversation can move — quickly and subtly — into specifics: clarifications, definitions, individual points of dispute. At first glance it can feel like progress. But it also does something important. It changes the frame.

When the Framework Is Applied

A behavior-based comparison — the school's own chart, placed next to the school's own documented reports.

Along with Christine's email to TSIS staff and families, a chart was shared distinguishing mentoring behaviors from grooming behaviors. So a natural question follows: what happens when that same framework is applied to the documented reports already collected by the school?

Not a Safe Place

A child, sitting alone on the pavement, looked up at the school building and said quietly: “This school is not a safe place.”

I heard screaming and sobbing on the basketball court. A young student — no older than seven — was curled into himself. I sat with him. After a few minutes, he whispered what stayed with me long after the meeting that followed: this school is not a safe place.

When the Pattern is Clear

Not a moment. Not a misunderstanding. Not a difference in interpretation. A pattern.

Documents shared, timelines established, statements compared. None of that changes what this has always been about. At this point, the question is no longer what happened — the documentation exists, the timeline is clear. The question is what will be done in response.
