“School of No” Principal Marcella Sills finally dragged herself into class on time Monday — sauntering through the doors at 7:30 a.m. in a bid to look good for investigators probing her failing and dilapidated PS 106.

“She hasn’t shown up that early in six or seven years,” a source said of the fur-clad boss of the Far Rockaway, Queens, school.

The school, located in Far Rockaway, has no art or gym classes, and students are frequently plopped in front of movie screens instead of learning.

Sills appeared to be scrambling like a failing student at finals time to put on a show for the city Department of Education probers who showed up following a series of Post exposés.

PS 106 earned its “School of No” moniker because, numerous school sources say, it has no gym, no art classes, kindergarten trailers that smell like animal urine and no reading, writing or math books for the rigorous Common Core curriculum.

Despite the squalor, Sills still forces parents — many of whom live below the poverty line — to cough up more than $200 to attend a bizarre, end-of-year prom in which fifth-graders must dress up like brides and grooms.

Also, sources say Sills frequently fails to attend work. http://nypost.com/2014/01/13/school-official-finally-investigates-nys-worst-elementary/
