The hospital’s mental services had been previously rated as good.
Alder Hey’s foundation trust said the upgrade reflected the “compassion, professionalism, and relentless commitment” of staff.
CQC inspectors said they found a dedication to giving children and young people a safe and caring service.
Inspectors found the services worked well with local schools to help deliver joined up and coordinated care.
Karen Knapton, from the CQC, said inspectors found “strong leaders, as well as kind and compassionate staff, who delivered high quality care”.
“Staff focused on what mattered to the people they were caring for, and as a result they felt valued and listened to.”
The overall rating for the trust remains unchanged and is rated as “Good”.
