臨床神經科學offer問題(DBS) - 留學

大家好

今天收到了UCL Clinical Neuroscience Msc的Conditional Offer(還沒考英文)
可能最近剛好不是申請旺季？
才線上申請了一個多星期就收到offer了。
(原本以為英國人的效率會拖個一個月之類XD)
但看了一下offer letter裡面有一段

It is a requirement of your offer that you meet the requirements for
clearance with the UK Disclosure and Barring Service (DBS) and/or clearance
from the relevant overseas authorities. Without clearance you cannot
undertake clinical work and/or gain access to restricted hospital data. This
requirement is in addition to the general condition concerning criminal
convictions and applies to all applicants admitted to the above programme of
study including those who are employed in a post that has previously required
a police check.

不知道有人知道這個DBS是怎樣嗎?
我需要在台灣申請無犯罪紀錄?還是學校會幫我申請調查我?
或者是之後去英國之後再申請？

想請問有人有過相關經驗可以告知嗎?
謝謝
