A new era in standardized testing of students begins Tuesday -- but this test is only a test.
California is starting its trial run of a new state exam to measure elementary, middle and high school students' performance each year. The test is meant to tap more sophisticated thinking and problem-solving skills than the familiar fill-in-the-bubble forms of old. Questions will gauge students' mastery of the Common Core Standards, the new national list of everything students should learn, adopted by California in 2010.
And, alas for the No. 2 pencil, the exam will be done entirely on computers.
That's cause for some anxiety among teachers, students and tech support staff around the state. Do all schools even have the technological capacity to deliver a 3.5-hour computerized exam? The trial run, which will reach different schools at different times through early June, aims to answer that question.
Small and rural school districts with weaker Internet service are girding for connectivity problems. The digitizing of the exam allows test-makers to include videos, interactive charts and graphics never seen in old-school tests, which modern students might appreciate. But that could further strain schools' capacity, even in urban settings.
