The state education board is doubling down on Maryland’s efforts to push the science of reading. The board on Tuesday unanimously adopted a resolution that would require all schools to have research-backed instruction by next school year, and also set an ambitious goal for Maryland to be one of the top 10 states for fourth-grade reading. “It’s not acceptable that we have more than half of our children that aren’t reading-proficient by the end of third grade, so we’ve got to create a sense of urgency about this,” said Carey Wright, the interim state superintendent.
