According to this, the Tavi has been moved into 3 out of 4. Looks like 4 is the lowest ranking.

"NEW: Tavistock and Portman NHS Foundation Trust is now subject to enhanced oversight from the NHS. It follows its Gender Identity Development Service being rated inadequate by CQC in January 2021 and an independent governance review finding several areas requiring improvement.
The arrangements came into place on April 1st, with the Tavistock moving into a category which requires a ‘Coordinated support package and enhanced oversight.’ It had previously been subject to the lowest possible oversight. Move is confirmed by the NHS North Central London CCG.
NHSEI allocates 213 hospital trusts in England to one of four segments: 'from no specific support needs (segment 1) to a requirement for mandated intensive support (segment 4).' 15 Trusts are in segment 4. The Tavistock joins 65 others in segment 3.

Frances O’Callaghan, Chief Executive Designate of the North Central London Integrated Care Board, said: “We are committed to working closely with the Trust to agree a clear action plan that will address current issues and support the delivery of high-quality care.”"
