There are two types of school records: the Mathetologion (Roll of Students) and the Genikos Elenhos (General Grade Book). The first is more reliable. Both show the student's name, father's
first name, school year, student's age, grade attended and month and day of registration.
Ages on school records are believed to have been given as of the age reached in the
calendar year of registration (the school year began in September).
Although 7 was normally the correct age for entering the first grade, many entered
as early as 5 or as late as 9. If a child entered before the minimum age (7), a fictitious
age (7) was often shown until the minimum age was met. In some cases, the first grade
may have meant a preschool class. Thus, for a variety of reasons, school records may
show 2-3 years attendance in the first grade.
If both a year of birth and age are shown, the year is more reliable.
