There are multiple reasons why students my not have access to an ILP.
For example;
Students may be newly enrolled in a school,
Students may be partial day students,
Students may have a duplicate SSID number in STI.
Schools should keep in mind the replication process and update process from the School STI system to the ILP system can take 2 -3 weeks. This could cause schools to not be able to view a students ILP during this time. When the school enrolls a student or corrects something in STI it will take a few weeks for it to show up in the ILP. This includes students transferring.
Schools should allow 2 weeks before they make a report that a student is missing.
