Escola Secundária de Barcelinhos (Barcelinhos Secondary School) is a public secondary school located in Barcelos, a town in the northwest of Portugal. It was founded in October 1986 and it has contributed to the education of thousands of students who live mainly on the left bank of the Cavado River. It is situated in a more rural area even though it is just 1 km away from the town of Barcelos.

Most students live in the surrounding villages which can be described as a mixture of countryside but slightly suburban in some areas. Most students come from families with a low-income. Some parents are farmers but the majority work in local factories or commerce. The school has classes from year 7 to year 12. Their ages range from 12 to 19. Currently there are 610 students grouped in 29 classes and there are 74 teachers. The largest group of students are of secondary level (10th to 12th
grades). Most students attend regular secondary courses, such as Sciences and Technology, Social and Economic Sciences and Languages and Humanities.

Vocational courses are also offered in three major areas: Tourism, Sports Management and ICT and Business Management. There are 20 students with special needs. There are no students who are refugees nor come from Roman families.
The majority of the students who attend the regular secondary courses are very interested in continuing their education in universities. Some of the vocational students also aspire to get a higher education and have succeeded in getting accepted in courses that are more technical. However, the majority of these vocational students start looking for a job after completing their secondary education. This school is a very dynamic one. Students are tested at a national level in subjects like Portuguese, Foreign Languages, Maths, Biology and Geology, Physics and Chemistry, Economy,
among others.

They can also participate in sports and scientific and cultural events through its clubs
and extracurricular activities: Sports Club (Desporto Escolar), Robotics Club, Erasmus+ Project, Drama Club, among others. The school also publishes its own yearly magazine, Schola, written by students, parents, teachers and staff. The school also participated for the first time in an Erasmus+ project in cooperation with three partner schools from Italy (project coordinator), Germany and Ireland. 

The school is equipped with computers, smartboards and projectors. Technology
is widely used in the classroom by the majority of teachers.
