A few days ago, we found out something quite interesting. With the arrival of September, schools and institutes prepare to start classes. Of course, they set their own schedulesThis means that the different modalities are gradually beginning. What happens? Well, we must have care With these kinds of numbers, if we get distracted we could even run into problems, such as losing school days, confusing the start of a stage, or not properly balancing work and family life.
Let's take an example. Keep in mind that almost every year, classes begin in mid-September. However, each year there can be a significant number of regulatory changes (due, above all, to educational laws and the planning of each autonomous community), which means that some schools have had to change their dates To begin with. Without going any further, sometimes communities like Valencia They have already started earlier than others, so currently, while some centers have not yet started, in other places they are already giving the first classes.
Who decides when classes start in schools and educational centers?

We must not forget that the start dates The classes depend, above all, on the autonomous communities, so they can reach to vary from one to the other. Each regional government publishes its official school calendarwhere they are fixed:
- The start and end dates of school activities at each educational stage.
- The vacation periods (Christmas, Easter and other mid-term breaks).
- The regional holidays and the additional non-school days.
- The margins for performing ordinary and extraordinary evaluations.
Although there is a fairly stable pattern (academic year from September to June, with a minimum number of school days While the start date is similar across the country, each region can move it forward or back a few days, or distribute holidays and non-school days differently. This means that families with children in different regions or who move from one region to another should pay close attention to official information.
Typical patterns of the start of the school year by educational stage
While it is essential to consult the specific calendar for each year and community, certain general patterns at the start of classes in schools and educational centers:
- Early Childhood Education (0-3 years)Publicly owned or publicly funded preschools and nurseries usually start in early September, and in many cases extend their activities until the end of June or even the end of July, to facilitate conciliation.
- Second cycle of Early Childhood Education (3-6 years) and Primary Education: Most commonly they begin in the first half of Septemberoften a few days before secondary school. They usually finish around midle June, after having completed the minimum number of school days.
- Compulsory Secondary Education (ESO) and BaccalaureateIn many calendars, they begin one or two days after preschool and primary school, also in the first half of September, and end around the second half of June. The students of the last courses (such as the second year of high school or final years of vocational studies) may end earlier depending on the entrance exams to college or other higher education.
- Vocational trainingBasic, intermediate, and advanced vocational training cycles usually begin classes very close to the start of compulsory secondary education (ESO) and upper secondary education (Bachillerato). In some cases, there are specific programs (second chance, specific training itineraries, etc.) which can start a few days later, but always within the framework of the first half of September.
- Artistic, sports, language and adult education coursesConservatories, art schools, official language schools, and adult education centers tend to have a slightly later start, often falling between the second week of september and the following weeks, with completion dates that may vary between mid- and late June, depending on the academic schedule.
This general scheme allows families to get a rough idea, but each community introduces its own nuances: some bring forward the start to gain more school days before the Christmas holidays, others compress the end of the school year more or adjust the artistic and sports teachings to their own evaluation needs.
School holidays, public holidays and non-school days
It's not just the moment that changes Classes beginbut also the way in which they are distributed rest periodsRegional school calendars always include three main sections:
- Christmas holidaysThey typically run from a few days before the Christmas holidays until after Three Kings Day. They often include around two full weeks, sometimes with an additional non-teaching day at the beginning or end, depending on weekends and national holidays.
- Easter holidaysThey usually extend between the Good Friday or Passion Friday and the Monday after Easter Sunday, although some communities extend or shorten this period. The duration is usually also around a week.
- Other non-school daysIn addition to national and regional holidays, the centers usually have several days of free disposal These days are spread across the three terms. They are approved at each school (usually with the participation of the school council) and must be communicated to families in advance. The following are also included: local holidays set by each municipality.
In some territories, periods such as the so-called āwhite weekā or breaks linked to carnivalwhich create long bridges that are especially relevant for organizing urban campsFamily activities or trips. These differences, although they may seem small, can greatly change the logistics of a family or an educational center throughout the school year.
Organization of schedules and school day in schools
In addition to the dates, each center defines its own work schedule model (partial or continuous) and the specific entry and exit times. In many places, September and June are developed with reduced working hours or with slightly different schedules than the rest of the course, which adds another layer of complexity:
- El School Board You can initiate procedures to modify the timetable model, but you need the participation and favorable vote of an absolute majority of families or legal guardians for the change.
- The centers can open their facilities before the start of school hours (for example, from early morning) to offer services of morning classroom without structured activities, paying attention and monitoring students according to their age.
- After the school day ends, the centers usually remain open until the afternoon for scheduling. complementary and extracurricular activitieseducational support or conciliation services.
- Sports and recreational facilities can, in many cases, also be open outside of school hours and even on non-school days, provided there is a project of use approved by the center, family associations or local administrations.
All of this means that, even within the same community, two schools can have very different schedulesTherefore, knowing precisely how each center organizes teaching and non-teaching time is as important as knowing the official start date of classes.
Importance of always consulting the study center

If you have any questions about the exact date When classes begin, we recommend that you contact your study centerAlthough the autonomous communities publish their official calendars, each school, institute, nursery school, conservatory or language school specifies:
- El day and time of incorporation of the students of each course or group.
- The possible staggered entrances (for example, specific days for 1st grade of Primary School, 1st year of Secondary School, new enrollments, etc.).
- The special hours of the first days of class and the organization of initial tutoring sessions with families.
- The internal calendars of ordinary and extraordinary evaluations in stages such as high school, vocational training or artistic studies.
They should already have everything ready for the start of the new school year, so they'll be able to tell you the exact day the children will arrive and all the details about the schedule, additional services (lunch, transportation, before-school care), and extracurricular activities. Staying informed through the school's website, notice boards, or official communications is the best way to avoid mistakes and face the start of classes at schools and educational centers with peace of mind and good planning.
Understanding how the school calendar is decided, the differences between regions, the distribution of holidays and non-teaching days, and the internal organization of each school allows families, students, and teachers to prepare for the school year in advance, optimize resources, and reduce unforeseen problems at one of the most important times of the academic year.
