The realistic timeline for adjustment
Most adjustment timelines follow a recognisable shape. The first two weeks tend to be high adrenaline: novelty, observation, social mapping, mild anxiety masked by excitement. Weeks three to six are usually the hardest. The novelty has worn off, the routines have not yet been internalised, friendships are tentative, and the cumulative cognitive load of the move catches up. This is the period where many parents start to worry.
Weeks six to twelve are the consolidation period. The child develops named friendships, the routines feel familiar, the academic content stops feeling foreign. By the end of three months, most children have a clear sense of who their friends are, what their daily routine looks like, and whether they like their school. A second adjustment dip often occurs around month five, when the initial honeymoon period gives way to a more honest assessment of whether the place is right. Most children come through this dip; some need more support.
By six months, the picture is usually settled. The child either belongs or they do not. The minority who do not usually show clear signs before six months. The work between months three and six is largely about reinforcing positive trajectories rather than instigating new interventions.
The first month: what to expect
The first week is dominated by school logistics: routines, buildings, names, lockers, timetables. Most children handle this competently and report back factually. Pay attention to the tone of the daily debrief rather than the content; flatness, exhaustion or selective silence often matters more than the specifics of what happened. Sleep more than usual; a five-year-old who is napping in the afternoon for the first time in two years is processing, not regressing.
Week two brings the first social tests. The buddy system that supported week one usually loosens, and the child needs to start choosing whom to sit with at break and lunch. By the end of week two, most children can name two or three classmates they have spent time with willingly. If they cannot, raise it with the form tutor; teachers can engineer pairings in week three but will not know to do so unless told.
Weeks three and four are when the early signs of either settling or struggling begin to show clearly. A child who is settling will start to use the names of teachers and classmates spontaneously, mention specific events from the school day without prompting, and develop tentative routines around break and lunch. A child who is struggling will avoid talking about school, regress on sleep or appetite, or show specific signs of distress before school each morning.
The home environment matters
What happens at home in the first three months has substantial effect on how the child adjusts at school. Three things tend to help. First, predictable routines around mealtimes, bedtimes and weekends. Children processing change need stable scaffolding; the more chaotic the household, the harder the school adjustment.
Second, sustained connection to the previous home. Phone or video calls with friends from the previous school, photographs of the old house, continued use of the home language, news from the previous community. Trying to replace the old context with the new context too quickly is counterproductive. Children settle better when they are allowed to hold both contexts in mind.
Third, a slow start on extracurriculars. Many parents over-schedule the first term in an attempt to help the child meet peers. The opposite is usually more effective: leave the first month largely free of after-school commitments, then add one activity in week five or six, then a second in week ten. Over-scheduling exhausts an already-tired child and reduces the home time they need to process the transition.

School-side support
Most international schools have structured systems for supporting new starters. The visible elements are the buddy system, the form tutor or class teacher relationship, the pastoral team, and the counselling service. The less visible elements are how teachers communicate with each other about a new starter, how often the school proactively contacts parents in the first months, and how the school escalates concerns.
The single most useful signal in the first six weeks is whether the school proactively contacts you with named observations about your child. Schools that say 'she sat next to Emily today and they seemed to get on' or 'he chose to read independently at lunch which is fine but worth watching' are doing the work. Schools that say nothing, or send only generic reports, are not.
If you have not heard from the form tutor by the end of week three, request a brief meeting or call. Be specific about what you want: not a general check-in, but two minutes of observation on how your child is settling socially and academically. Do this calmly and without pressure; the goal is information, not escalation. For wider context on what a strong school looks like, see our piece on what to expect on your child's first day.
Friendship formation
Friendships at the new school usually form in two phases. The first phase is the convenience phase: friendships of proximity, often with whoever sits next to your child in class or whoever is on the same school bus. These usually form within the first two to three weeks and may not last.
The second phase is the affinity phase: friendships based on shared interests, temperament or sense of humour. These take longer, often six to twelve weeks, and form through extracurricular activities, school trips, and the slow accumulation of shared experience. The affinity friendships are usually the durable ones. A child who has not yet found affinity friends at week eight is not necessarily struggling; some children take longer to make the right matches, and the wait is usually worth it.
What you can usefully do at home is create opportunities for one-to-one or small-group contact outside school. Hosting a single classmate for a Saturday afternoon is more useful than a large group activity. The depth of one good friendship matters more than the breadth of acquaintance.
Common warning signs
Most children adjust within the normal range. A minority do not. The warning signs worth attending to are: sustained tears at drop-off beyond week four, regression in sleep or appetite that persists beyond two weeks, a refusal to talk about school at all, specific reports of social difficulty that recur over several weeks, somatic complaints such as recurring stomach aches or headaches with no obvious medical cause, and any specific reports of bullying or social exclusion.
Two or three of these signs together, persisting beyond week four, is reason to engage actively with the school. One sign in isolation is usually normal adjustment. The judgement call is whether the cluster of signs is stable, escalating or declining; declining is normal, stable is concerning, escalating requires action.
Mental health considerations are real. International school children typically face wellbeing challenges that domestic-school children do not, and the cumulative load of the move can compound pre-existing anxiety or low mood. See our piece on mental health support at international schools for further context.
When to seek extra support
Three thresholds usually justify external support. First, persistent signs of distress beyond week six that have not responded to home and school adjustments. Second, regression that worsens over time rather than improving. Third, any disclosure by the child of self-harm thoughts, severe social distress, or active refusal to attend school over multiple days.
External support options include the school counsellor, the school's referral network to private clinicians, and family doctors who can refer onwards. Most international schools maintain a relationship with English-language mental health practitioners in the city. Use these networks; they exist for this purpose.
Be cautious about waiting too long. The longer a struggling child waits for support, the harder the recovery becomes. The cost of seeking professional input early when it turns out not to be needed is low; the cost of waiting too long when it is needed is high.
Adjustment for younger versus older children
Younger children, particularly those between four and seven, usually settle faster than older children. They form friendships more easily, are more flexible about social hierarchies, and adapt to new routines more readily. The risks are more emotional than social: younger children may struggle to articulate distress and need more parental observation rather than parental questioning.
Middle-school children, between eight and twelve, often have the hardest adjustment. They have enough social awareness to feel acutely the difference between belonging and not belonging, but they have not yet developed the resilience and self-management of older teenagers. Friendships at this age are unstable, social hierarchies are forming, and the cognitive load of school is rising. Expect adjustment to take six to twelve weeks rather than two to four.
Teenagers, particularly between thirteen and fifteen, settle more variably. Some adapt quickly, particularly if they find a peer group through extracurriculars or shared interests. Others struggle more visibly, particularly if the previous school was a strong source of identity. Older teenagers in the final two years of secondary often settle academically faster but socially slower; some retain their previous-school social ties through travel and online contact, and accept the new school as a transactional place rather than a home.
FAQ
Most children adjust within three to six months. The first two weeks are usually high adrenaline; weeks three to six are often the hardest. By twelve weeks, most children have a clear sense of friendships and routines. A second adjustment dip around month five is common and usually passes.
Sustained tears at drop-off beyond week four, regression in sleep or appetite, a refusal to talk about school, recurring physical complaints with no medical cause, and any specific reports of bullying or social exclusion. Two or three of these together, persisting beyond week four, warrants active engagement with the school.
Yes. Sustained connection to the previous home, including video calls with friends, photographs of the old context and use of the home language, helps rather than hinders adjustment. Trying to replace the old context too quickly is counterproductive.
When signs of distress persist beyond week six without improvement, when regression worsens rather than improving, or when there is any disclosure of self-harm thoughts, severe social distress or active school refusal. Use the school's referral network; do not wait.
