Texas schools will be allowed to boost their graduation rates by as much as 3 percentage points by 2020, the state’s education commissioner said Tuesday, a milestone that would mark the first time in decades that Texas has achieved such a dramatic increase.

Education Secretary Dee Dee Lewis said that if approved by voters in November, the policy would require Texas schools, which have been hit hard by the state government shutdown, to increase graduation rates, a move that she called “a step in the right direction” but said “should not be considered a mandate.”

“We’ve been working hard to create a culture where every student gets the opportunity to graduate,” Lewis said.

“We can achieve that through education.

But we also know that if we do not make sure that our students are graduating in the way they are, then they’re not going to have a future.”

Texas schools have struggled under the leadership of Gov.

Greg Abbott, who has struggled to make good on promises to improve graduation rates.

During his first term, the Legislature passed $300 million to create an overhaul of the state education system and was expected to raise the graduation rate by 3 percentage degrees, from 3 percent to 3.5 percent, by 2020.

The new formula would raise the school-age graduation rate from 72.3 percent to 75.9 percent by 2020 and the student-teacher ratio from 10.6 to 10.7.

It would also give each teacher a pay raise of $8.75 an hour by 2020 over what the average teacher earns.

Abbott has also pledged to cut teacher pay by 50 percent by 2025.

The state’s most populous school district, Dallas-Fort Worth, is expected to increase its graduation rate to 80.5% in 2020 and is the only one of Texas’ two largest districts to achieve a graduation rate of at least 90 percent.

The Dallas-Sugar Land district, which has the highest student-to-teachers ratio in the state, is also expected to achieve graduation rates of up to 90.5%.

The Dallas-area school district has been working on a plan for two years to achieve the 3% goal, which requires schools to offer students a higher education beyond the bachelor’s degree or master’s degree.

The district plans to increase the number of students who complete the bachelor and master’s degrees by about 10% by 2020 but is still evaluating the effectiveness of the plan.

The Dallas district has had to work on a different strategy.

Its plan calls for expanding the number and quality of instruction and creating a teacher workforce that would bring in more qualified teachers and increase the ratio of students completing the bachelor degree or higher to 10%.
