The Department of Education (DepEd) has analyzed the classroom requirements based on the latest classroom inventory and enrollment data of schools along with the standard parameters for the computation of requirements by the DepEd Planning Service. To date, a total of 123,994 classrooms are still needed to be constructed in all public elementary and secondary schools with remaining classroom requirements. As shown in the table below, Region IV-A (CALABARZON), National Capital Region (NCR), Region III (Central Luzon), and Region VII (Central Visayas) are the top regions with the highest classroom shortages.

The top regions mentioned above have the most cities or municipalities that are classified as highly urbanized. These areas have large populations mainly due to being sites of business centers in the country where employment or business opportunities are high, and therefore where many people choose to reside. This is the reason why the school-age population is also high in these areas, resulting in high enrollment rates in schools within their scope.
The graph above and the table below shows the distribution of the classroom shortage in NCR and Region IV-A. As shown in the tables, Taguig and Rizal have the highest number of classroom shortages in NCR and Region IV-A respectively.

Recently, neighboring regions of the National Capital Region (NCR) were made into relocation areas. Displaced families from places where infrastructure developments are ongoing were moved to identified relocation areas in Regions III and IV-A, contributing to an increase in the school-age population in the said regions.
Schools from these areas have become congested as their existing facilities are no longer sufficient to cover the increasing requirements of the growing population of learners. Another challenge is that even if the national government has been prioritizing the construction of school buildings in its annual budget, the limited or lack of buildable space in schools located in these highly urbanized areas has not allowed the programming and construction of school building projects.
SITE ACQUISITION ISSUES
In the effort to address the classroom shortage in the National Capital Region, Regions III, IV-A, and VII, the Department has been acquiring additional school sites in these regions for the past five years.
From 2016 to 2020, a total of only 15 new school sites were acquired through the Department’s Site Acquisition Funds. However, while there are still funds for the purpose, albeit totally insufficient, DepEd is finding it difficult to look for sites that can be acquired. This is mainly due to the following:
- no more available sites;
- cost of sites in urban areas is too high and the site acquisition budget provided is not enough; and
- if there are available sites, land owners are unwilling to sell their property to DepEd because of the lower commercial value.
At this juncture, it is worthy to mention that the annual appropriation of P65,000,000 (from 2017 to 2021, saved from 2016 and 2019 where increases were provided) for Improvement and Acquisition of School Sites is meager and wanting—not even enough to cover the Titling of school sites. It seems that in the distribution of tasks and mandates, land acquisition falls under Local Government Units, and through donations of private groups and/or individuals, practically leaving DepEd with no say on the locations, nor the freedom to exercise prudence in choosing hazard-free areas.
Acquisition of School Sites from 2016 to 2021
ADDRESSING THE CLASSROOM REQUIREMENTS
In order to determine the direction and proper action in addressing the classroom issues in these specific regions, a series of consultations were conducted with Regional Directors, school leaders, and other counterparts within the Department. Two ideas were presented:
Transporting Learners to other nearby schools or to schools to be constructed in neighboring towns/cities with large buildable spaces
This concept is about balancing the volume of learners that a school caters to. If a certain school has a large volume of learners that it can no longer accommodate, other learners can be referred to other nearby schools that are open and can still accept and cater to additional learners.
New school buildings may be constructed in neighboring cities or towns that have schools with large buildable areas. Learners will be bused in from their residence to these schools.
However, this will require the full support and assistance of local government units (LGUs). Parents have to be informed about the proposal and assured that their children will be safe while being transported to and from the assigned nearby school. Assistance from LGUs will be sought for the provision of transportation for the learners.
Construction of High-Rise School Buildings
The first idea presented may be considered an option for the different regions, depending upon the approval of their various stakeholders. However, it is not the most practical solution to address the problem of classroom shortage. Thus, the concept of constructing high-rise school buildings was formed. Given the limited sites available for schools to acquire and build on, this concept is the most acceptable solution, provided that a sufficient budget is available for the purpose. Likewise, assistance from the LGUs shall be sought for the maintenance of the structure once it is completed.
CONCEPT OF HIGH-RISE SCHOOL BUILDING DESIGNS
The proposed medium to high-rise school building design is intended to be constructed in highly urbanized areas where there is a dense population but limited land areas for development.
The proposal will have varied designs ranging from at least 5 floors to as high as 12 floors, or even higher. The number of floors will depend on the required classroom needs of the school, the available building space, the type of soil, and the projected enrollment population for the next 15 to 25 years.
The new school building design takes into account the effects of climate change and global warming as it introduces green and sustainable tropical design principles to mitigate the negative effects to our environment. Passive cooling, site adaptation, and building layout to comply with the ideal “East-West” orientation will be given utmost importance to avoid dependence on artificial means of ventilating the building.
Compliant with National Building Code requirements and other laws pertaining to structural stability, fire safety, vertical conveyance, and utility requirements, the new school building design is meant to address school requirements for both academic and non-academic facilities.
Below are some salient design features for the high-rise school buildings:
A. Green Sustainable Design
- Passive Cooling approach – window openings shall be oriented to North and South, to reduce heat penetrating the building interiors.
- Maximized Daylighting and Natural Ventilation – natural light and wind will be allowed to enter the corridors on each floor. High windows will be installed along the walls fronting corridors to allow cross air ventilation as well as natural lighting in the corridor area.
- Water Efficiency
a. Use of Water Efficient Sanitary Fixtures – through water-saving toilet fixtures
b. Rainwater Harvesting System – rainwater from roofs will be collected and reused as gray water for toilet flushing, cleaning, and maintenance purposes
- Energy Efficiency
a. Use of Energy Efficient Lighting Fixtures (LED) – to reduce power consumption but still achieve required room illumination levels
b. Use of Renewable Energy/Photovoltaic cells (Solar Panels) -maximize the use of solar panels on roofs
- Use of locally available building materials – commercially available construction materials to be used
- Flood Mitigation
a. Elevated Ground Floor – to avoid floodwaters from entering the ground floor level in flood-prone areas.
B. Building Design
The high-rise school building design will promote Heritage Architecture by incorporating the architectural features of Gabaldon School Buildings of colonnaded and arched entrance porticos.
C. Accessibility for the Handicapped
The design will be compliant with B.P. 344 or the Act to Enhance the Mobility of Disabled Persons by the provision of ramps, PWD toilets, elevators with Braille Elevator Signage System for the blind and visually impaired. Tactile Guide Pathways as floors tiles shall also be introduced.
All balconies shall have vertical metal tubular elements as a safety feature to avoid students from falling or jumping from the ledges.
E. Typhoon Resiliency

GENERAL CONSTRUCTION METHODOLOGY OF HIGH-RISE SCHOOL BUILDINGS
The advantage of having a small building footprint for the new high-rise school building is that during implementation, only a few existing buildings will be affected depending on where it will be located within the school campus.
Demolishing fewer existing buildings to give way to new construction will be advantageous to the school as classes will not be disrupted and may still be held in the remaining school buildings unaffected by the construction. There will be less dislocation of students and faculty, and to compensate for the affected buildings, the school may choose to do limited double shifts of classes until the new high-rise building is completed and turned over to the school.
PRIORITY CITIES AND TOWNS
Below are the Top 10 target areas with classroom shortages for High-Rise School Buildings. The Top 9 cities have more than 1,000 classroom shortage except Rodriguez, Rizal with 898.
The project is proposed to be implemented under the Multi-Year Contractual Authority (MYCA) since the construction of this type of high-rise school building will definitely take more than a year to complete.
It is strongly suggested that this project immediately commences in 2022 as part of the Legacy Program of President Rodrigo Roa Duterte by appropriating at least 6 billion pesos to implement the project.
All LGUs willing to partner with the national government and all other basic education stakeholders are welcome and encouraged to join this noble endeavor.
It is also suggested that an appropriate Public-Private Partnership (PPP) for School Infrastructure Project (PSIP) be designed for high-rise school buildings to enable the private sector to participate in solving the perennial problem of classroom shortage, provided the same designs shall be adopted and implemented.
Amid shifting demographics and the changing needs of the times, it is with urgency and great optimism and that this proposal for the construction of high-rise school buildings is presented.
With singleness of purpose, we can hope, as one nation, timely address and overcome the recurring shortage of classrooms — leaving a legacy to our Filipino learners and advance Basic Education in the country.
