There's an increase in the number of students graduating from the Baltimore City Public School system.Graduation numbers out on Friday show it's the largest increase the city has seen in almost a decade.The Class of 2018 is the first in a long time to make headlines based on the success it had in the classroom.It didn't take long for Baltimore City to get the word out that it's four-year graduation rate was starting to climb among students across the board. Last summer, 72.2 percent of students got diplomas, which is 1.5 percent more than the year before. It represents a 10.7 percent hike since 2010."A lot of that goes to our students, who have persevered, worked hard, sometime have to go to summer school, sometimes have to do extra work, but they've done a great job," said John Davis, chief of schools for Baltimore City. The smallest group to graduate students struggling to learn English, or English language learners, recorded a 51.2 percent graduation rate. That's a gain of a little over than 10 percent in only a year's time."There's always room for improvement," said Marietta English, president of the Baltimore Teachers Union. English says the much-improved numbers are proof the administration, principals, teachers and support staff are all on the same page."They work very hard to see that our kids are getting what they need, in spite of the fact that they don't have all the resources that they need," said English. School officials say the jump is due in part to a long-term strategy it believes will pay off with the class of 2019.While there are slightly more Baltimore City students graduating, there are also fewer of them dropping out of school.
