A clínica credenciada faz a avaliação psicológica.

Here, A means the, not a.

In Portuguese, a can be:

• an article meaning the before a feminine singular noun
• a preposition meaning to, depending on context

In A clínica credenciada..., clínica is a feminine singular noun, so a is the feminine singular definite article: the.

So:

• a clínica = the clinic
• uma clínica = a clinic

Because clínica is a feminine noun in Portuguese.

Many nouns ending in -a are feminine, and clínica is one of them. Because it is feminine, words that describe it usually also appear in the feminine form.

That is why you get:

• a clínica
• credenciada (not credenciado)

Credenciada agrees with clínica in gender and number.

• clínica = feminine singular
• so the adjective/past-participle-style modifier must also be feminine singular: credenciada

Compare:

• o hospital credenciado = the accredited hospital
• a clínica credenciada = the accredited clinic
• as clínicas credenciadas = the accredited clinics

In this sentence, credenciada works like an adjective meaning accredited, authorized, or certified depending on context.

In this context, credenciada usually means something like:

• accredited
• authorized
• officially approved
• registered with an institution or system

For example, in medical, insurance, or administrative contexts, a clínica credenciada is often a clinic that has been approved by a company, government body, or professional organization.

Because faz is the conjugated form of the verb fazer in the present tense.

• fazer = to do / to make
• faz = does / makes for ele/ela/você

The subject here is A clínica credenciada, which is grammatically third person singular, so the verb must also be third person singular:

• A clínica faz... = The clinic does/carries out...

Some present tense forms of fazer:

• eu faço
• você/ele/ela faz
• nós fazemos
• eles/elas fazem

Portuguese often uses fazer in situations where English might prefer a more specific verb like carry out, perform, or conduct.

So:

• faz a avaliação psicológica can naturally mean
• does the psychological evaluation
• performs the psychological evaluation
• conducts the psychological evaluation

In formal contexts, you may also see:

• realiza a avaliação psicológica

That can sound a bit more formal or technical, but faz is perfectly normal.

That second a is also the definite article the.

So the sentence contains two separate articles:

• A clínica = The clinic
• a avaliação psicológica = the psychological evaluation

Portuguese often uses the definite article in places where English also uses the, but sometimes Portuguese uses articles more frequently than English does in general.

Because the sentence refers to one evaluation, so the noun is singular:

• a avaliação = the evaluation
• as avaliações = the evaluations

The whole sentence is talking about a single act or service: the clinic performs the psychological evaluation.

Psicológica describes avaliação.

So:

• avaliação = evaluation
• avaliação psicológica = psychological evaluation

Just like credenciada, psicológica must agree with the noun it describes:

• avaliação = feminine singular
• therefore psicológica = feminine singular

Compare:

• teste psicológico = psychological test
• avaliação psicológica = psychological evaluation

In Portuguese, adjectives usually come after the noun.

So the most natural order is:

• avaliação psicológica

not usually:

• psicológica avaliação

This is one of the basic word-order differences from English, where adjectives normally come before the noun.

Very generally:

• English: psychological evaluation
• Portuguese: avaliação psicológica

Yes. The subject is A clínica credenciada.

Breakdown:

• A clínica credenciada = subject
• faz = verb
• a avaliação psicológica = direct object

So the structure is:

[Subject] + [Verb] + [Object]

This is the normal word order in Portuguese, just like in English.

Yes. That is a very natural translation.

Even though fazer literally often means to do or to make, in context it can sound more natural in English as:

• performs
• conducts
• carries out

So possible translations include:

• The accredited clinic does the psychological evaluation.
• The accredited clinic performs the psychological evaluation.
• The accredited clinic conducts the psychological evaluation.

Depending on the context, the second or third option may sound more natural in English.

Avaliação is pronounced approximately like ah-vah-lee-ah-SOWN in Brazilian Portuguese, with the stress on the last syllable.

The ending -ção is very common in Portuguese and often corresponds to English -tion:

• avaliação = evaluation
• informação = information
• situação = situation

So if you recognize -ção, it can help you spot many abstract nouns.

Yes. Some natural alternatives are:

• A clínica credenciada realiza a avaliação psicológica.
• A avaliação psicológica é feita pela clínica credenciada.
• A clínica autorizada faz a avaliação psicológica.

These all keep a similar meaning, though the tone or emphasis may change slightly.

For example:

• realiza sounds a bit more formal than faz
• é feita pela... changes the sentence to a passive structure
• autorizada is similar to credenciada, but not always identical in nuance
