SLCP verifications can be announced, semi-announced or unannounced. This will depend on the facility's decision. When announced, the date(s) of the onsite verification are communicated. When semi-announced, the Verifier will determine a wider timeframe (usually 10 days or more) in which the verification will occur. Unannounced means the facility will not know when the Verifier is coming for verification.
We understand that (semi)announced verifications are preferred to ensure that the facilities have all the documentation ready, and all the people available, for when the Verifier arrives onsite. The facility may reach out to business partners to see what method of announcement they prefer for acceptance of SLCP reports.
