student performance vs student's performance

[uktous]

Hi,

Question:
Should I say student performance or student's performance?

Sentence:
My aim was to improve student performance / student's performance.

Thanks

You can use either student performance or students' performance.

Unless you really only had one student.

Unless you really only had one student.

any difference between student performance and students' performance?

when should I use student performance?
when should I use students' performance?

Not much- you could think of student performance as being general and student's performance relating to specific students.
