Performans değerlendirmesi gelecek hafta yapılacak.

A fairly literal breakdown is:

• performans = performance
• değerlendirmesi = its evaluation / evaluation of it
• gelecek hafta = next week
• yapılacak = will be done

So the whole sentence is literally something like The performance evaluation will be done next week.

In natural English, that could also be The performance review will take place next week.

Because this is a very common Turkish noun pattern called an indefinite noun compound.

• performans değerlendirmesi = performance evaluation
• first noun: performans
• second noun: değerlendirme
• the second noun takes the compound ending: -si

So:

• değerlendirme = evaluation
• performans değerlendirmesi = performance evaluation

This pattern is extremely common in Turkish:

• çocuk kitabı = children’s book
• yemek masası = dining table
• iş görüşmesi = job interview

Even though English often uses two bare nouns together, Turkish usually marks the second noun in this structure.

Structurally, the ending -si can look like a possessive ending, and historically it is related to one. But in this sentence, you should understand performans değerlendirmesi as a fixed noun-compound meaning performance evaluation, not necessarily his/her evaluation.

So here it is best translated as:

• performance evaluation
• performance review
• performance assessment

not literally as its evaluation in the usual English sense.

Yes, gelecek can mean will come, but it can also function as an adjective meaning coming or next.

Here:

• gelecek hafta = the coming week / next week

So in this sentence, gelecek is not the main verb. It is describing hafta.

Compare:

• Ali gelecek. = Ali will come.
• gelecek hafta = next week

Same form, different function.

Turkish often uses bare time expressions without a case ending when saying when something happens.

So:

• gelecek hafta = next week
• yarın = tomorrow
• pazartesi = on Monday

That is normal Turkish.

You would use other case endings only if the grammar specifically requires them in a different structure. But for a simple time expression like next week, the bare form is the usual choice.

Yapılacak comes from the verb yapmak = to do / to make.

It breaks down like this:

• yap- = do, make
• -ıl- = passive
• -acak = future

So:

• yapacak = will do / will make
• yapılacak = will be done / will be made

In this sentence, the passive is important because the sentence does not say who will do the evaluation. It just says that it will be done.

Turkish, like English, often uses the passive when the person doing the action is unknown, unimportant, or simply not mentioned.

So:

• Performans değerlendirmesi gelecek hafta yapılacak. = The performance evaluation will be done next week.

This sounds natural if the speaker wants to focus on the event itself, not on who will carry it out.

If you wanted an active sentence, you could say something like:

• İnsan kaynakları performans değerlendirmesini gelecek hafta yapacak.
• HR will do the performance evaluation next week.

In one sense, performans değerlendirmesi is the grammatical subject of the passive sentence, because it is the thing that will be done.

But Turkish does not need an explicit agent in passive sentences. So the sentence does not say who will perform the evaluation.

That is completely normal.

You can think of it like English:

• The report will be sent tomorrow.
• We do not know from the sentence who will send it.

Same idea here.

Because Turkish normally places the finite verb at the end of the sentence.

So the order here is:

• Performans değerlendirmesi = topic/subject
• gelecek hafta = time expression
• yapılacak = verb

This verb-final order is one of the most important basic patterns in Turkish.

English says:

• The performance evaluation will be done next week

Turkish naturally prefers:

• Performance evaluation next week will-be-done

Yes. Turkish word order is flexible, although some orders sound more neutral than others.

The given sentence is very natural:

• Performans değerlendirmesi gelecek hafta yapılacak.

You could also say:

• Gelecek hafta performans değerlendirmesi yapılacak.

This version puts more focus on next week.

In both cases, the verb usually stays at the end in a neutral statement.

No article appears in this sentence, because Turkish does not have direct equivalents of English the and a/an in the same way.

So performans değerlendirmesi can be understood from context as:

• the performance evaluation
• a performance evaluation
• the performance review

In this kind of workplace sentence, English will often use the, because the situation sounds specific. But Turkish does not need a separate word for that.

Performans is a loanword and is very commonly used in modern Turkish, especially in business, education, and HR contexts.

So performans değerlendirmesi is a normal, natural expression for things like:

• performance evaluation
• performance assessment
• performance review

Turkish uses many such borrowed words, especially in professional language.

Depending on context, the most natural English translations could be:

• The performance evaluation will be done next week.
• The performance review will take place next week.
• The performance assessment will be conducted next week.

If this is an HR context, performance review is often the most natural English choice.

You would make the passive future negative by adding -ma- before the future ending:

• yapılacak = will be done
• yapılmayacak = will not be done

So:

• Performans değerlendirmesi gelecek hafta yapılmayacak.
• The performance evaluation will not be done next week.

In Turkish, yes/no questions usually use the question particle mi.

So:

• Performans değerlendirmesi gelecek hafta yapılacak mı?
• Will the performance evaluation be done next week?

Notice that mı/mi/mu/mü is written separately.

It comes from the verb değerlendirmek, which means to evaluate / assess.

Very roughly:

• değer = value
• değerlendirmek = to evaluate
• değerlendirme = evaluation

Then in the compound:

• değerlendirme → değerlendirmesi

So the sentence contains a noun derived from a verb, just like English evaluate → evaluation.

In modern Turkish, ğ usually does not sound like a strong consonant. It often lengthens the surrounding vowel or creates a smooth transition.

So değerlendirmesi is not pronounced with a hard g sound.

You do not say it like English deg-er...

Instead, it sounds more like a softened, flowing vowel transition. Exact pronunciation can vary a bit by speaker and region, but the important point is:

• ğ is usually silent or lengthening
• it is not a normal hard g

Yes.

• gelecek hafta = next week
• önümüzdeki hafta = next week / the upcoming week

Both are common. Önümüzdeki hafta can sound slightly more like the upcoming week, while gelecek hafta is a very direct next week.

So you could also say:

• Performans değerlendirmesi önümüzdeki hafta yapılacak.

That would mean essentially the same thing.
