- +3 Science
- +1 Science for every 2 Citizens in this City.
- 1 Scientist Specialist Slot
- +1 Gold with Sovereignty Social policy
- +1 Happiness with Academy of Sciences Order tenet
The Public School is a very effective Industrial-era building much like the Library. It greatly increases a city's scientific output. Requiring that a city already have constructed a University or Wat, its main effect is to provide additional Science based on the number of Citizens. With the Library, this leads to 2 Science per person.
It also has a wide variety of small bonuses. First, it provides a Specialist slot (additional +2 Science and increasing Great Scientist potential), as well as a token +3 Science increase on the building itself. With the Humanism policy, it will also provide 1 Happiness; with the tree complete, its maintenance will be reduced to 2 Gold per turn (down from 3).
Altogether this is a strong building, especially for large, Tradition cities and empires, where the ratio of production and maintenance to the output is highest. With Rationalism, this building becomes even easier to support and take advantage of. Policies combined, it can easily output as much as 20 Science in one city before percentage boosts. Outside their Capital, Liberty empires may not get as much use out of these buildings until Rationalism completes, but will likely want a few more heading into the later Eras. An existing Public School is required for the later Research Lab.
A public school provides free pre-university education to a civilization's children. This is a fairly advanced concept. First, the civilization must believe that education is important, and that educating the poor is not a threat to the ruling class. Second, the civilization must be wealthy enough so that the children of the poor do not need to work to fend off starvation. And finally, the civilization must be enlightened enough to be willing to expend some of its public revenue providing the education. Most countries in the world today provide some level of public education for their young. The first American public grade schools opened during the Colonial era. The first public high school was opened in Boston in 1821.
