With a winter storm potentially closing or delaying many Massachusetts schools Tuesday, the MCAS English Language Arts Composition test for students in grades four, seven and 10 has been postponed until Monday, March 25, the Massachusetts Department of Elementary and Secondary Education announced on its website. 

The test was scheduled for Tuesday.

But in an effort to make sure all schools administer the test on the same day, "all schools must administer the ELA Composition test to students in grades 4, 7, and 10 on Monday, March 25, including schools that are not affected by the weather," according to a memo from Elizabeth Davis, associate commissioner of student assessment.

If there is school on Tuesday, any ELA Reading Comprehension test sessions that are scheduled may be administered, just not the ELA Composition test.
