If you have tendered for an immigration contract from April, you will be required to provide details of your supervisors by the start date. Failure to do so will result in contract offers being withdrawn. A supervisor in immigration is required both  to hold the level 2 accreditation and to have passed the supervisors exam. CLT, the assessing organisation, have brought forward the announcement of supervisor exam results from the planned date of mid April into March so that those firms who are depending on a potential supervisor passing the exam will be able to verify their supervisor before the deadline. They are asking that any candidates who also need to pass the level 2 accreditation or re-accreditation contact them so that arrangements can be made to expedite the release of results for those exams as well. See the announcement on the Law Society website for more.
