Аттестация дала мне обратную связь.

Because аттестация is a feminine noun in Russian, and past-tense verbs agree with the subject in gender and number.

• аттестация = feminine singular
• so: дала = gave (feminine singular)

Compare:

• Экзамен дал мне обратную связь. = The exam gave me feedback.
  (экзамен is masculine, so дал)
• Аттестация дала мне обратную связь. = The assessment gave me feedback.
  (аттестация is feminine, so дала)

Мне is the dative case of я (I).

Base form:

• я = I

Dative form:

• мне = to me

In Russian, the person who receives something is often put in the dative case. Since the sentence literally means something like The assessment gave feedback to me, Russian uses мне.

So:

• дала мне = gave me
• literally: gave to me

Because обратная связь is the direct object of the verb дала, so it goes into the accusative case.

Dictionary form:

• обратная связь = feedback

In this sentence:

• обратная → обратную (feminine accusative singular)
• связь stays связь

So:

• nominative: обратная связь
• accusative: обратную связь

This happens because дать (to give) takes a direct object:

• gave what? → feedback

This is a normal pattern for many feminine nouns in Russian.

• обратная is an adjective, and feminine adjectives usually change in the accusative:
  • -ая → -ую
• связь is a feminine noun ending in a soft sign ь, and for this type of noun, the accusative singular is often the same as the nominative singular if the noun is inanimate.

So:

• nominative: обратная связь
• accusative: обратную связь

Only the adjective visibly changes here.

Аттестация can mean something like:

• assessment
• evaluation
• certification review
• attestation

The exact English translation depends on context. In workplace or educational contexts, it often refers to a formal evaluation process.

So this sentence could mean:

• The assessment gave me feedback
• The evaluation gave me feedback

A native English speaker should note that аттестация is often more formal and institutional than a casual test or review.

Yes. Обратная связь is the standard and very common Russian expression for feedback.

It is used in:

• education
• work
• performance reviews
• communication
• customer response
• technical contexts

Examples:

• Спасибо за обратную связь. = Thanks for the feedback.
• Мне нужна обратная связь. = I need feedback.

You may also hear фидбек in informal business or IT speech, but обратная связь is the normal standard Russian phrase.

Russian has no articles like a/an or the.

So аттестация can mean:

• an assessment
• the assessment

and обратную связь can mean:

• feedback
• the feedback

You figure out whether it is definite or indefinite from context.

That is completely normal in Russian.

Yes. Russian word order is more flexible than English word order because case endings show grammatical roles.

The neutral order here is:

• Аттестация дала мне обратную связь.

But other orders are possible, depending on emphasis:

• Мне аттестация дала обратную связь.
  Emphasizes to me
• Обратную связь мне дала аттестация.
  Emphasizes feedback
• Дала мне обратную связь аттестация.
  More marked or stylistic

Even though the order can change, the basic meaning stays the same because:

• аттестация is the subject
• мне is dative
• обратную связь is the direct object

The infinitive is дать, which means to give.

Here are some related forms:

• дать = to give
• дал = gave (masculine)
• дала = gave (feminine)
• дало = gave (neuter)
• дали = gave (plural)

So in your sentence:

• Аттестация дала... = The assessment gave...

Russian often uses дать in places where English might use:

• give
• provide
• offer

So дала мне обратную связь is very natural Russian and means:

• gave me feedback
• provided me with feedback

Russian tends to use simple, common verbs very naturally in these situations.

Yes, связь can mean connection, link, communication, or contact depending on context.

But обратная связь is a fixed expression meaning feedback.

Literally, it is something like:

• reverse communication
• return communication

Over time, this became the standard term for feedback.

So you should learn обратная связь as a whole phrase, not by translating each word separately every time.

Yes, that is grammatically correct.

Compare:

• Аттестация дала мне обратную связь.
  Neutral, straightforward
• Аттестация мне дала обратную связь.
  Slight extra emphasis on мне

Both are natural. The first one is probably the most neutral and standard version for a learner to copy.

In Russian, обратная связь is grammatically singular:

• эта обратная связь = this feedback
• полезная обратная связь = useful feedback

English feedback is uncountable, but Russian treats обратная связь as a normal singular noun phrase.

So Russian says:

• Я получил обратную связь. = I got feedback.

not because it means one feedback, but because that is simply how the concept is expressed grammatically in Russian.
