WHAT YOU SHOULD KNOW

Cherelle Parker will be inaugurated as Philadelphia’s first female mayor a ceremony at The Met Philadelphia on Tuesday. Parker is scheduled to speak at about 11:50 a.m.

Parker is already officially the mayor — she privately took the oath of office on Monday.

Kevin J. Bethel will be sworn in as Philly’s new police commissioner at Russell Conwell Middle School in Kensington at 1 p.m. Parker is scheduled to attend.

Familiar faces and an unusual structure: All of Parker’s 17 appointees named so far are from Philly or have worked in politics or government here.

Parker has worked with a trio of informal advisers who have mostly flown under the radar since her history-making victory.
