Buscábamos para nuestros tres hijos, un colegio que ofreciera un curriculum internacional Americano y óptimas instalaciones deportivas. Clases reducidas, un porcentaje muy alto de profesorado y alumnos internacionales dentro de un entorno natural y familiar. Nuestra valoración después de tres años en el colegio es excelente.

Trabajé como profesora de secundaria en GRESOL durante un trimestre y la verdad es que, al margen de problemas comunes a todos los centros que se vieron potenciados por la pandemia, tuve una experiencia positiva.El ambiente es bueno, aunque el volumen de trabajo es muy elevado. El claustro de secundaria es atento y se preocupa por el alumnado. Además, el currículum se adapta y amolda a necesidades concretas de alumnos.

Un excelente equipo docente, de múltiples nacionalidades, y una gran apuesta por la educación en artes y ciencias. Recientemente ha obtenido la certificación de Bachillerato Internacional.
Yo la he llevado este año, de momento muy contenta con el proyecto y con la profesora. Tenía buenas referencias de otros alumnos y además había leído mas opiniones en otras webs (buscocolegio). Decir que el proyecto ha cambiado hace un par de años por lo que puede haber opiniones negativas de antes del cambio. Estoy teniendo muy buena impresión, calidad en la educación, cercanía. Inmersión lingüistica en inglés, aprenden música como en conservatorio, segundo idioma alemán..etc.. Por ahora todo positivo.

Escogimos este colegio porque buscabamos un colegio que ofreciera metodo educativo, clases en ingles, curriculum internacional e instalaciones. Gresol nos ofrece esto y mas. Clases reducidas, entorno natural y mucha musica. Como en todos los colegios, hay cositas a mejorar pero la direccion esta abierta a escuchas a las familias y esto no abunda en los colegios privados. Colegio muy recomendable e indispensable visitar por todas aquellas familias del Valles que quieran una educacion de calidad para sus hijos.

Frequently Asked Questions about GRESOL International-American School

These are some of the common questions and answers from parents interested in our American international private school.

It is a secular school with an international and American curriculum, whose educational project is based on the premise of immersion in English. It is a private school, with a global vision and multicultural thinking, that promotes knowledge in the arts, sciences, music and technology.

GRESOL International-American School is part of an international platform of projects that expands our vision and internationalizes it. A project that will be strengthened and consolidated thanks to the achievements of the entire GRESOL team and families.

We are accredited by:

-. COGNIA, the world leader in certifying educational institutions that strive for excellence. COGNIA serves more than 36,000 institutions in over 85 countries worldwide, educating more than 25 million students.

-. and by ib, a prestigious and recognized worldwide organization, based in Geneva, which articulates and regulates a single standard curriculum for all schools, regardless of where they are located.

Its curriculum is recognized by most of the world’s universities, allowing students who obtain the ib DP direct access without the need for prior official university entrance exams.

In addition, we have become the first international school in Spain to sign a cooperation agreement with PennWest Pennsylvania University (formerly Clarion University of Pennsylvania), one of the best universities in education and pedagogy in the United States.

A 100% English immersion education means that the language of instruction for most subjects is English. Logically, other languages are taught at GRESOL: Catalan as the language of Catalonia, Spanish as the language of Spain as a whole, and French and German as the fourth and fifth languages.

English as a foreign language is taught in all public and charter schools, as well as in many elite schools.

At GRESOL, English is the central and vehicular language for almost all subjects. For example, math classes are taught in English by a native teacher, science classes are taught in English, and physical education classes are taught in English. GRESOL students do not learn English, they learn IN English. For them, English is the language of daily expression, they will think in English in the same way that, in Catalonia, they already think in Catalan or Spanish when they use one language or the other.

At the earliest ages, students develop their basic skills as they explore the world around them. We offer activities that encompass all aspects of children’s learning: language and literacy, cognitive and creative skills, performing and visual arts, social and emotional development.

In Primary, we encourage students to communicate effectively, to be critical thinkers, to cooperate and collaborate constructively, in a welcoming environment. The educational approach is based on the idea of student-centered learning, awakening the student’s curious mind. Educational experiences are engaging, relevant, challenging and meaningful to the school community. In Elementary, the curriculum is aligned with US Common Core and adapted to the needs of our students.

English (ELA); Visual and Performing Arts; Personal, Social, Emotional and Physical Education; Science; Social Science; Mathematics.

Yes, indeed. In Catalonia we have a very easy way of understanding it: English will be like Spanish for a Catalan speaker, or like Catalan for any Catalan who usually speaks Spanish. For a GRESOL student, the facility to switch languages and communicate in English will be the same as in the two official languages of Catalonia. This generates a wealth of opportunities for the future.

Studies confirm that good use of languages, preferably English, is one of the skills most sought after by companies today. Even more so, considering the new paradigm that lies ahead of us, in which English will be essential.

From 0 to 3 years of age, the brain is in the process of developing and maturing, and this is the most intensive period in the acquisition of speech and language skills. That is why more and more parents are investing in their children’s future by enrolling them in a school with 100% English language immersion from kindergarten, or even earlier. If it can be from kindergarten, so much the better.

There are more than 7,000 different languages spoken in the world, according to the publication ‘Ethnologue’. And among them, the official language spoken in the most countries is English, with 59. Therefore, learning languages improves communication and relationships between people, in addition to stimulating our brain. That is why the more languages you learn, the better. In addition, adding languages to a child’s native language, no matter how young, does not interfere with learning. Children can learn two, three, even four languages from an early age, which will favor their predisposition and ease of learning more.

In addition to English, the language of instruction at GRESOL International-American School, classes are also taught in Catalan, as the language of Catalonia; Spanish, as the language of Spain as a whole; and there is also the option of studying French and German, as the fourth and fifth languages.

As an international school, GRESOL prioritizes teaching in English, with 100% immersion in the language. But GRESOL does not forget, logically, Catalan and Spanish.

An international school is one that promotes international education, in an international environment, either by adopting a curriculum such as the International Baccalaureate or by following a national curriculum different from that of the school’s country of residence. In our case, we offer two options: graduating with the International Baccalaureate and/or the National Baccalaureate. And, all of this, studying in English without the need to leave Spain.

An international and American school such as GRESOL International-American School offers not only language teaching and practice, but also a deeper learning, for more and better understanding, and with a different skill development. For this it is essential to be immersed in the language, beyond studying it a few hours a week in an academy.
