LISD high schools operate on an accelerated block schedule. This means that students take four 90-minute classes each day as a full schedule with a full credit class being completed in two 9-week terms. You may schedule VLA classes as one or more of your four classes during periods 1, 3, or 4. We do not normally schedule VLA classes during the daily attendance period, which is currently period 2. Taking a class outside the school day would mean the student is taking a 5th class scheduled for period 00 or 8.
