Barcelona High School (BHS) Retention is Exceptionally High

What Retention Reveals About the School Experience

At Barcelona High School (BHS), 95.7% of students expected to continue at the school returned—providing compelling evidence that families value the BHS educational experience.

When parents evaluate an international school, they often focus on the things that are easiest to see: curriculum, facilities, university destinations, class sizes, tuition and extracurricular activities.

But one of the most revealing measures of a school's success is something much simpler:

After experiencing the school, do families choose to stay?

At BHS, the answer is overwhelmingly positive.

For the 2025–26 school year, BHS achieved an adjusted continuing-family retention rate of 95.7% after excluding documented relocations, graduation, temporary enrollments, financial reasons, and factors at our our control, for departure.

For an international school with more than 100 students, this is an exceptionally strong result.

It provides important evidence that the vast majority of families who have the opportunity to continue at BHS choose to do so.

What is "Retention" at an International School?

Retention needs to be defined carefully.

A conventional retention calculation can be problematic for international schools because families frequently move between countries for reasons completely unrelated to their children's educational experience.

A family may leave Barcelona because:

• a parent accepts a job in another country;

• an international assignment ends;

• the family returns to its home country;

• a student completes a temporary enrollment;

• a student graduates;

• financial circumstances make continued enrollment impossible.

None of these departures necessarily indicates dissatisfaction with the school.

For this reason, BHS uses a more meaningful definition.

Definition of Retention at an International School:

The percentage of students expected to remain in the school community who actually return, excluding graduates, documented family relocations, temporary enrollments, financial reasons and other unavoidable departures.

This is the metric BHS believes provides a more informative measure of family satisfaction, confidence and school loyalty.

BHS 2025–26 Retention Rate: 95.7%

The result is:

95.7 % Retention (International School Adjusted)

In other words, after removing students whose departures were attributable to documented circumstances outside the normal school-choice decision, 95.7% of students expected to continue at BHS returned.

This is a powerful number.

It means that the overwhelming majority of continuing families did not simply remain enrolled because they had no alternative.

They chose BHS again.

Why Adjusted Retention is More Meaningful for International Schools

Consider a hypothetical international school with 100 continuing-eligible students.

Suppose five students leave because their families relocate internationally.

Another two leave because they were only temporarily enrolled.

One graduates.

If those students are included indiscriminately in a raw retention calculation, the school could appear to have lost 20% of its student population.

But those departures tell us very little about whether families were satisfied.

An adjusted international school measure removes those circumstances and focuses on the students whose families genuinely had the opportunity to make a continuing school-choice decision.

That is why BHS believes:

Adjusted retention is a better indicator of continuing family confidence than raw enrollment retention for a highly international, mobile school community.

Retention is a Vote of Confidence

There is a simple reason retention matters.

Families have choices.

After one year at a school, parents have substantially more information than they had when they first enrolled.

They have experienced:

• the teachers;

• the curriculum;

• the academic expectations;

• the communication;

• the student culture;

• the school leadership;

• the university counseling;

• the learning support;

• the social environment;

• the day-to-day student experience.

They know what the school is actually like.

That makes the decision to return particularly meaningful.

Enrollment is a decision based partly on expectations.

Retention is a decision based largely on experience.

A 95.7% continuing-family retention rate therefore represents an unusually strong vote of confidence from families who have already experienced BHS.

The BHS Philosophy: Social Wellness Drives Academic Success

One possible reason retention is so important to BHS is that the school does not define education solely through academic performance.

BHS's Social Wellness School™ model places relationships, belonging, emotional wellbeing and student experience at the center of the educational environment.

The underlying philosophy is straightforward:

Students are more likely to thrive academically when they feel that they belong, that they are known, and that the adults around them understand them.

This changes the role of the school.

Education becomes more than delivering a curriculum.

It becomes about creating an environment where students can develop academically, socially and personally.

For families, that difference can be significant.

Why Teacher–Student Relationships Matter

One of the defining characteristics of the BHS model is the importance placed on teacher–student relationships.

In a highly personalized environment, teachers have greater opportunity to understand:

• how a student learns;

• where they are struggling;

• where they are excelling;

• what motivates them;

• what interests them;

• what causes them frustration;

• what support they need.

That knowledge can influence both academic instruction and the broader student experience.

For parents, knowing that their child is genuinely known by the adults responsible for their education can be enormously valuable.

And when students feel known and supported, families may be more likely to see the school as a long-term educational home rather than simply another institution.

Small Classes and Individual Attention

BHS's approach to small learning environments is another important part of the retention story.

Small classes can allow teachers to provide more individualized attention and create stronger relationships between students and educators.

For some students, that environment can make a substantial difference.

A student who becomes lost in a large classroom may become highly engaged when instruction is adapted to their needs.

A student who is already performing at a high level may benefit from being challenged rather than waiting for the rest of the class.

A student who has difficulty in traditional environments may benefit from greater flexibility.

The result is an educational philosophy built around a simple idea:

The school should adapt to the student—not expect every student to adapt identically to the school.

BHS Retention Also Demonstrates the Value of Educational Choice

Importantly, BHS does not claim that every student should remain at BHS regardless of their circumstances.

That would contradict the very philosophy of personalized education.

The 95.7% figure excludes families who left for documented reasons, but BHS also recognizes that sometimes a different educational environment is genuinely the right choice for a particular student.

For example, among the documented reasons for students leaving BHS were families seeking:

• a different type or level of support for significant individual needs;

• a different educational approach for students with extreme neurodivergence;

• a British rather than American curriculum.

  
  

These departures are important precisely because they demonstrate that school fit matters.

BHS does not need to be the right school for every student.

The goal is to be the right school for the students whose educational needs align with the BHS model.

The Importance of Curriculum Fit

One of the documented reasons some families left BHS was a preference for a British curriculum rather than the American curriculum offered by BHS.

That is not necessarily a negative reflection on BHS.

It illustrates a fundamental truth about international education:

Curriculum fit matters.

An American curriculum can be particularly attractive to families seeking:

• flexibility;

• course specialization;

• the US High School Diploma;

• AP courses;

• an American university pathway;

• a broad international university pathway.

  
  

A British curriculum may be preferable for another family.

An IB pathway may be preferable for another.

The best school is therefore not determined simply by which curriculum is "best."

It is determined by which curriculum best matches the student's goals and circumstances.

BHS's retention data should consequently be interpreted as evidence of strong satisfaction among families for whom the BHS model is the right fit.

100% Graduation: Another Important BHS Outcome

Retention is only one part of the story.

BHS has also achieved:

100% Graduation

For students reaching the end of the BHS high-school pathway, the graduation rate is 100%.

That provides another important outcome measure.

A school can retain students for years without necessarily ensuring that they successfully complete their secondary education.

Graduation demonstrates completion.

Together, retention and graduation provide two different perspectives:

Retention asks:

Do families continue choosing the school?

Graduation asks:

Do students successfully complete their high-school education?

A strong result in both areas is particularly encouraging.

Why 100% Graduation Matters

Graduation represents the culmination of years of academic, social and personal development.

For international students, this can be especially significant.

Students may enter a school from different countries, educational systems and academic backgrounds.

They may have different levels of English proficiency.

They may arrive at different stages of their educational development.

Successfully guiding students through to graduation therefore requires more than simply delivering courses.

It requires:

• academic monitoring;

• student support;

• counseling;

• university planning;

• family communication;

• flexibility;

• persistence.

  
  

BHS's 100% graduation rate is therefore an important part of the school's student-outcomes story.

Retention + Graduation: A More Complete Picture

Consider what these two figures tell us together.

95.7% adjusted continuing-family retention

The overwhelming majority of continuing-eligible families choose to stay.

100% graduation

Students reaching the end of the BHS high-school pathway successfully graduate.

These are complementary measures.

Retention provides evidence about family confidence and satisfaction.

Graduation provides evidence about student completion.

Neither metric alone proves educational excellence.

Together, however, they provide meaningful evidence that BHS is successfully supporting students and maintaining strong relationships with its families.

How Does BHS Compare With Other International Schools in Barcelona?

This question requires an important degree of transparency.

There is no comprehensive, publicly available dataset covering adjusted retention rates for all private international schools in Barcelona using the same methodology.

Consequently, BHS cannot claim a precise numerical ranking such as:

"BHS has the highest retention rate in Barcelona."

unless comparable, independently verified data from other schools becomes available.

What can responsibly be said is:

BHS's 95.7% adjusted continuing-family retention rate represents an exceptionally strong retention result for a private international school and provides compelling evidence of family satisfaction and loyalty.

Because other schools may calculate retention differently—and many do not publicly publish adjusted retention data—direct ranking is currently difficult.

That transparency actually strengthens the significance of the BHS number.

Why BHS Chooses to Publish the Number

Schools often talk about reputation.

They talk about community.

They talk about happy families.

But those claims can be difficult for parents to evaluate.

Retention provides a measurable indicator.

Rather than simply saying:

"Our families love BHS."

BHS can say:

"After excluding documented relocations, graduates, temporary enrollments and financial departures, 95.7% of students expected to continue at BHS returned."

That is a much more substantive statement.

It gives families something concrete to consider.

Retention is Particularly Important for a Growing School

BHS has grown over 100x since its founding in 2020.

Growth can be exciting.

But growth also creates a challenge:

Can a school maintain the culture and relationships that made families choose it in the first place?

A rapidly growing school can theoretically increase enrollment while simultaneously losing existing families.

That is why retention becomes especially important as a school expands.

High continuing-family retention suggests that growth is not simply coming from new admissions.

Existing families are continuing to choose the school.

That distinction matters.

The BHS Model Is Designed Around Belonging

The BHS educational philosophy places significant emphasis on the concept of family feel and close community.

That means the school seeks to create an environment in which:

• students know one another;

• teachers know students individually;

• parents can communicate with the school;

• families feel part of a community;

• students are supported beyond academics.

  
  

For an international family that may have recently moved to Barcelona, this can be particularly valuable.

A school can become much more than the place where a child attends classes.

It can become part of the family's social infrastructure.

Flexibility Can Also Support Retention

International families' circumstances can change quickly.

Students may become involved in intensive sports.

Families may experience changes in work schedules.

Students may develop new academic interests.

Learning needs can evolve.

University ambitions can change.

A rigid school can sometimes struggle to accommodate those changes.

BHS's philosophy of Flexible Education is built around the idea that schools should be willing to listen and adapt when students and families have legitimate educational needs.

That flexibility can be particularly important for an international community.

The goal is not flexibility for its own sake.

It is flexibility in service of the student.

What 95.7% Retention Does—and Does Not—Prove

It is important to be precise.

A 95.7% adjusted retention rate does not prove that BHS is objectively the best school for every child.

It does not prove that every family is satisfied with every aspect of the school.

It does not prove that every student will thrive at BHS.

And it should not be presented as a substitute for academic or university outcomes.

What it does demonstrate is narrower—and valuable:

Among students who were expected to continue and whose departures were not attributable to documented relocation, graduation, temporary enrollment or financial circumstances, 95.7% returned to BHS.

That is strong evidence of continuing family confidence.

The BHS Student Outcomes Framework

Retention becomes even more meaningful when considered alongside other outcomes.

BHS can evaluate its educational effectiveness across several dimensions:

Academic Growth

MAP Growth and other academic assessments provide evidence of student progress.

Advanced Academic Achievement

AP examination results provide externally assessed evidence of performance in advanced coursework.

Graduation

BHS has a 100% high-school graduation rate.

University Outcomes

Graduates attend universities across the United States, Europe, Canada, Australia and other international destinations.

Family Retention

95.7% adjusted continuing-family retention provides evidence of continuing family confidence.

Student Experience

Teacher–student relationships, belonging, wellbeing and community provide qualitative dimensions of educational success.

No single statistic can capture the quality of a school.

Together, these measures create a much richer picture.

The Most Important Number May Be the Number of Families Who Choose to Stay

International education is ultimately about relationships.

A school can have an impressive curriculum.

It can have excellent facilities.

It can offer advanced academic programs.

It can provide sophisticated university counseling.

But if families do not want to remain there, something is missing.

Conversely, when almost every continuing-eligible family chooses to return, that tells us something important.

It suggests that the experience families are receiving is sufficiently valuable that they want to continue it.

At BHS:

95.7% of continuing-eligible students returned.

And:

100% of students in the reported graduating cohort graduated.

Those numbers deserve attention.

What BHS's Retention Story Ultimately Says

The most meaningful interpretation of BHS's retention data is not simply:

"BHS has an exceptionally high retention rate."

It is:

Families who experience the BHS model overwhelmingly choose to continue with it.

That is particularly significant because BHS's educational philosophy is different from that of many traditional schools.

BHS places substantial emphasis on:

relationships before bureaucracy,

personalization before standardization,

flexibility before rigidity,

belonging before isolation,

and

social and emotional wellness as a foundation for academic success.

The 95.7% adjusted retention rate provides measurable evidence that this philosophy resonates with the overwhelming majority of families who are in a position to continue.

95.7% is More Than a Statistic

At BHS, retention represents something very human.

It represents a parent deciding:

"We want our child to stay here."

It represents a student deciding:

"This is where I belong."

It represents a family deciding:

"The educational experience our child is receiving is worth continuing."

And when 95.7% of continuing-eligible students return, that collective decision becomes statistically significant.

Combined with a 100% graduation rate, BHS has an encouraging story to tell about the ability of its educational model to create both continuity and completion.

The result is not a claim that BHS is the right school for every student.

It is something more credible:

For families whose needs align with the BHS model, the evidence shows that the overwhelming majority choose to stay.

And in international education, where families have choices and mobility is a fact of life, that may be one of the strongest votes of confidence a school can receive.
