Is the word escolas the same in Brazilian and European Portuguese?

Yes

The word "escolas" is identical in meaning, spelling, and grammar in both Brazilian and Continental Portuguese. The only differences are in pronunciation and collocation (the specific words naturally paired with it). In Brazil, the vowels are generally more open and the rhythm is more melodic, while in Portugal, the vowels are more closed or reduced. Additionally, while "escolas" remains the same, the adjectives used to describe them often change (for example, Brazilians use "particulares" while Portuguese people use "privadas").

Brazilian Portuguese Examples:

1. As escolas particulares são muito caras. (Private schools are very expensive.)
2. As escolas vão entrar de férias amanhã. (The schools are going on holiday tomorrow.)
3. Eu procuro boas escolas para os meus filhos. (I look for good schools for my children.)
4. As escolas públicas precisam de mais investimento. (Public schools need more investment.)
5. As escolas estão em reforma. (The schools are undergoing renovation.)
