When your family lives abroad, there are a range of educational options available to choose from. For some families and some students, boarding school is a really great option worthy of consideration. And yet there are also horror stories many of us have heard, which can make this decision particularly fraught for parents who are trying to make the best choices for their families. 

In this article, I present four findings from TCK Training’s research on the experiences of TCKs who primarily attended boarding schools. These TCKs formed 12% of the total group of 1,904 TCKs in our 2021 survey.

1) Boarding school is linked to higher mobility.

High mobility turned out to be a very important factor in our research. TCKs who experienced extreme mobility (10+ location moves or 15+ house moves) were much more likely to report four or more Adverse Childhood Experiences (ACEs) – a risk factor associated with negative outcomes in adulthood. 1 in 3 highly mobile TCKs had a high risk ACE score, compared to 1 in 5 TCKs overall.

TCKs who primarily attended boarding school had higher levels of mobility in every metric we measured. They lived in more countries, moved location more often, and moved house more frequently. Statistically speaking, a boarding school TCK could expect to move locations at least once every two years throughout childhood. In addition, nearly half of boarding school students moved house more than 10 times before age 18, compared to one third of all TCKs. 31% of boarding school students reported extreme location mobility, and 26% reported extreme house mobility. Only 5% of boarding school TCKs moved house fewer than five times during childhood.

These high rates of extreme mobility among boarding school students are not surprising, but the correlation of high mobility with high ACE scores means we need to take these transitions very seriously.

An additional impact of boarding school mobility is attachment between parent and child. When boarding school is keeping parent and child apart for too long, it risks damaging important family bonds.

The Limits of Parental Separation chart from the book High Risk: Children Without A Conscience by Magid and McKelvey (1989) is a great reference for how to manage separation of parents and children without damaging attachment; this work is regularly referred to in devising custody arrangements. It can also be helpful in safely managing a boarding situation without damaging attachment. For example, the preferable limit for 6-9 year olds is two weeks’ separation from a parent, and the harmful limit is four weeks’ separation from a parent. For a 10-13 year old, it is four and six weeks, and for a 14-18 year old, it is six and nine weeks.

2) Boarding school is linked to abuse – sort of.

The survey results linked to abuse among TCKs can be difficult to read. This section includes statistics of various types of abuse, but no descriptions of or stories about that abuse.

Boarding school TCKs have higher rates of abuse than missionary kids (MKs), but lower rates than other TCKs. The majority of boarding TCKs in our survey were MKs, making this noteworthy.

In our 2024 survey, we asked TCKs more detailed questions about their childhood experiences of abuse and neglect, including what happened in their schools. We look forward to learning more about what boarding school students have experienced as we analyze the data we have collected – stay tuned to learn more in 2025.

What we learned from our 2021 survey was that the rate at which boarding school TCKs experienced childhood abuse dropped dramatically over time. For those born after 1980 (Millennials and Gen Zs), boarding school TCKs actually had lower rates of abuse in the home than TCKs overall (11% vs 16% for physical abuse; 33% vs 43% for emotional abuse).

Over time, reported rates of all types of abuse decreased. Boarding school TCKs born after 1980 were less than half as likely to be physically abused at home (11% vs 27%), and only one third reported emotional abuse at home, compared to nearly half of older boarding school TCKs (33% vs 49%). Sexual abuse also decreased, though only from 29% to 24%.

The survey also asked about experiences of child-to-child sexual abuse and grooming, although these are not included in the Adverse Childhood Experiences questionnaire. In both areas, the older generation of boarding school TCKs reported the highest rate of the five educational groups. The rate dropped among younger boarding school TCKs, however.

The message here for parents considering boarding school is twofold. First, schools are learning from problems in the past; our survey results show that younger generations of boarding school students are at lower risk than their older counterparts. Second, no school experience is entirely safe – even homeschooling. We live in a broken world and cannot prevent all harm from coming to our children. Yet we do our best to protect children through education (for ourselves and also for them) and by carefully scrutinizing the child safety policies and education that prospective schools have in place.

3) Boarding school is linked with fewer mental health issues in parents.

Living with an adult who is depressed, mentally ill, or attempts suicide is an Adverse Childhood Experience (ACE), one reported by 39% of the TCKs we surveyed but only 32% of boarding school TCKs. Not only that, while every other educational sector showed a sharp increase in the percentage of TCKs reporting household adult mental illness, the rate among boarding school TCKs actually decreased. 

We hypothesized that boarding students may be less aware of their parents’ mental health concerns as they are not home all the time. That said, it is also worth recognising that some families are choosing between homeschool and boarding school due to their remote location – and  homeschool can be really stressful for some families. In these cases, boarding school may be the healthiest option available. 

4) Boarding school is linked with ongoing relationships.

One of the most important ways to proactively care for your kids is through Positive Childhood Experiences (PCEs). Many of these are connected to relationships, and this is an area where boarding school can be a gift. Having supportive friends, feeling a sense of belonging in high school, taking part in regular traditions, and having two non-parent adult mentor figures are four of the eight PCEs – and they are ways that boarding schools can give stability to TCKs.

Here’s one TCK’s perspective on boarding school life: 

I made close friends that I kept close for many years. My dorm had the same people; we didn’t get anyone new until 10th Grade. We had a full house; it was the largest dorm, with about 17 kids, plus the dorm parents’ three kids. All the way up until 11th Grade we had the same brothers and sisters in my dorm.

When a TCK is deeply impacted by transition – whether they are constantly moving or whether they are seeing people move in and out constantly – boarding school can be an option to offer some relational stability. For TCKs living in remote areas, boarding school can offer the opportunity to make friends in ‘real life’ rather than over a screen. This is equally true for mentor-figures, which is another essential part of a well-rounded childhood.

As I explained in my book, Misunderstood:

Adults who teach and supervise at boarding schools and boarding houses have a huge impact on TCK students. TCKs I interviewed who made close pseudo-family connections with boarding school staff coped much better than those who were less connected. (Source: Misunderstood: The Impact of Growing Up Overseas in the 21st Century, p 87)

TCK Training's research shows that TCKs do better when they have peers their own age and that their closest friends almost always speak their native language. Boarding schools are sometimes the best option to provide these friendship opportunities.

In conclusion: there is no right (or wrong) answer for TCK education.

A comfort for parents considering boarding school is that younger TCKs who attended boarding schools had fewer Adverse Childhood Experiences than those in the past did. 

Another thing our research shows is that every schooling type comes with some level of risk. There is no perfect choice. Instead, make the best decision for your family — knowing that the best choice for your family may be different to the best choice for another family.

If you can make a choice that limits mobility, that might be a good way to limit risk. If there is a choice that lowers stress for any/all family members, that’s probably a good sign. If you can make a choice that ensures your child has access to friends and belonging, that could be a good way to improve the odds of a positive outcome.

Whatever schooling choice(s) you make, it is important to learn about preventive care, such as how to care for kids in a way that protects them from unintended emotional abuse and neglect. It’s all too easy to unintentionally ignore our children’s needs when we ourselves are under stress from transition, moving locations, and dealing with the weight of everything involved in an international life. In addition, we need to know who is caring for our kids – at home and at school – and make sure they are educated about being emotionally healthy and safe.

In addition to avoiding causes of Adverse Childhood Experiences (ACEs), we can promote Positive Childhood Experiences (PCEs). When a child has 6+ PCEs, this buffers them from the negative effects of even a high ACE score. Responding to your child’s feelings, making them feel safe, and ensuring they are connected to peers, mentors, and communities, really does make a lifelong difference!
