could you please check the sentence /what vs which/

[jamieee]

Responsible for moving the team to accomplish its task what/which is processing and assessing students’ applications for bursaries.

[Barb_D]

Responsible for moving the team to accomplish its task what/which is processing and assessing students’ applications for bursaries.

"What" is definitely wrong. If you use "which," use a comma after task.

Better would be: Responsible for moving the team to complete the processing and assessing of students’ applications for bursaries.

Or: Responsible for moving the team to accomplish its task: processing and assessing students’ applications for bursaries.

Is "moving the team" common phrasing? Instead of "motivating" or "leading"?

Can you say: Led the team responsible for the processing and assessing of students’ applications for bursaries? Or Led the team that processed and assesse students’ applications for bursaries?

This is an abbreviated style, of the kind used on resumes. If it's a resume, fewer words are better than more words.
