A D.C. school bus driver and attendant who left a student with special needs alone on their vehicle for hours on Tuesday ignored set protocols — including disengaging a safety buzzer with an off switch at the back of the bus — and overlooked the 4-year-old boy, who stayed on the bus between the morning and afternoon runs, city officials said.

D.C. school officials on Thursday praised overall gains in 2012 test scores as another baby step toward the ambitious, long-term goals for school reform — although less than half of the city's students were proficient in math and reading.

Standardized test scores from three D.C. classrooms were invalidated because teachers helped students choose the right answers or flouted security protocols in April 2011.

When Gina Arlotto's children meet classmates at D.C. public schools, they sometimes get invited to pool parties at their new friends' homes out in Maryland.

Recent test scores show long-term improvement among D.C. students, despite concerns about cheating and a dip in reading proficiency this year at the elementary school level, city officials said.

The District has invalidated 2010 standardized test scores from three D.C. public school classrooms, citing clear evidence of violations or a "strong suspicion" of them, the city's Office of the State Superintendent of Education said Wednesday.
