At some point, while teaching at a mostly-immigrant elementary school in Brooklyn, we started to get a slew of students with questionable educational backgrounds. Many school systems have systems to screen new students with gaps in their education. At the time, the one for elementary school students in NYC consisted of one question to parents as to whether the student had been to school before, which was completely insufficient. Many students go to school, but are in and out to work or because of weather or other interruptions. Other families are worried about ramifications of being truthful about their child's schooling, so they lie or inflate their answers. Regardless, it's important for teachers to be able to identify a child as SIFE (Student with Interrupted Formal Education), and this series of questions, administered in the child's home language, can really help ensure students are given the intervention they need.
