River Trails School Dist. 26 officials said they became aware of affecting student information dating back to 1997. The district received a letter from Pearson, a British-owned education publishing and assessment service for schools and corporations. The student data affected includes first and last names, and in some instances, dates of birth and email addresses. No grade or assessment information was affected, according to Wagner. The district has contacted all families of impacted students for whom they have contact information.
