The star in the logo stands for the perfection of the human person as well as the search for truth, while the five concentric circles depict infinite wisdom.
Both the five-pointed star and the five concentric circles stand for quintessence, meaning the highest form of quality or the most perfect example of creation.
The star is golden yellow not only because this is a star's natural color but also because, together with the dark maroon used as background, it is the traditional color of the University.
The five concentric circles are white because it symbolizes purity.
The Centenary Logo is an emblem of a noble and glorious past, a living testimony to the University population's adherence to the beautiful traits of loyalty, integrity, love of peace, commitment to service, and undying love of and devotion to God - essential attributes in the pursuit of academic excellence and progress in a span of one hundred years (1904-2004).
Standing for the wheel of life is the circle which moves incessantly to give life to all members of the academic community - the administrators, the professoriate, the non-academic personnel, and the studentry - walking hand in hand, regardless of status in life, looking forward to a resplendent life-giving future. As it is, the wheel of life converges with Information and Communications Technology.
The laurel leaves inside the circle embody good health, peace, harmony, and prosperity within the ambit of PUP and the global village where the inhabitants meet as they communicate the same ideals, ideas, and aspirations.
Within the centenary logo is the PUP logo which speaks eloquently of PUP's vital role in molding minds, enriching souls, and giving firmer grounds to stand on.
From the circle emanate three big arrows which stand for the rapid growth of high-tech education in all levels. The University is now cited as the Center of Development in different disciplines, especially Information and Communications Technology.
From the Philippine Flag spring red and blue bands - a symbol of the PUP community's respect for nationalism and Filipinism, strengthened by the PUPians' role in nation-building, courageous outlook, tenacity and contribution to economic progress.
The rising sun emerges through the yellow color imbibing the vision, mission, and goals of PUP and its endless search for truth, excellence, quality, compassion, efficiency and effectiveness as it tackles the functions of a University - instruction, research, extension, and production.
Ten small arrows spring from the circle to herald the University's concern for people from all walks of life, through the service and commitment in seven branches and three campuses throughout the nation.
