Mayor announces computer science education for all city schools

Mayor Bill de Blasio announced Thursday that computer science classes are coming to all city schools.
The mayor says that before this school year, less than 5 percent of city public school students learned computer science in their classrooms. He says the administration is now rolling out an $80 million initiative to bring computer science classes to nearly 1.1 million students in New York City public schools. 
Officials say $20 million has been secured from the private sector for the program. They say 450 teachers have been trained to teach computer science, with a goal to have 5,000 in city schools.
"One of the key things of success has been how enthusiastically teachers have gone through professional development," says School Chancellor Carmen Farina.
Mayor de Blasio says it will take about 10 years to roll out the new program in its entirety.
According to officials, the technology industry has grown 57 percent between 2007 and 2014.
Computer science classes currently are being offered in 246 elementary, middle and high schools across the city.
