Информика 6.0 Школьный — лучшее ПО 2012 г. по версии PC Magazine
Семейство дистрибутивов для образовательных учреждений (разработаны ФГАУ ГНИИ ИТТ «Информика» и ООО «Альт Линукс»), содержащее все необходимое ПО для создания инфраструктуры учебного заведения. Главная особенность этой системы — интеграция рабочих мест учащихся и преподавателя. Учитель может не только централизованно управлять учебным процессом, но и общаться с учениками в привычной нынешнему поколению форме чатов и форумов. Сообщения могут содержать задания, их решения и комментарии, возможен обмен файлами любых форматов как между преподавателем и учащимся, так и между учащимися.
