Baroness Walmsley - Liberal Democrat Spokesperson in the Lords for Children, Schools and Families, comes under scrutiny in this pre-election debate series which challenges MPs from the three main political parties on their education pledges.
Joan takes the hot seat and is questioned over the pledges her party has made, including the pupil premium, class sizes and the Education Standards Authority.
She faces questions from a panel of school staff, in a debate hosted by journalist Mike Baker.
The panel is made up of award winners from the field of education; headteacher of the year in a London school, Catherine Myers, primary teacher of the year Steve Mills, teaching assistant of the year Trish Gribble, and governor of the year Spyros Elia.
