Second grade (called Grade 2 or Class 2 in some countries) is a year of primary education in many nations. Second grade is the second grade of primary school. The school age is depending on which country, and depending if the students have repeated the first grade or not.
In Brazil, the minimum age required to enter second grade is 7 years old.
In Cameroon, there are two sub-educational systems, one based on French education taught in French and the other one based on British educational systems taught in English. So, in Cameroon this grade will correspond to "Class Two", for the English sub-educational system. That correspond to the second year for the kids in primary, however, most of them have spent 2 to 3 years in nursery school. In the French speaking school, this will correspond to the "Cours preparatoire (CP)".
In France, it would correspond to CE1 (Cours Élémentaire 1) which is the second year of elementary school. This course used to be known as 10ème.
In India, children enter Class 2 or 3 at ages 7 to 8.
In Italy, it corresponds to second class of primary school (seconda classe della scuola primaria)
In Germany, this would be comparable to second class (2.Klasse)
In Greece, it is the Second grade of Primary (Deftera Dimotikou).
In New Zealand, this level of class is called Year 3. Children generally start this level between the ages of seven and eight.
In Peru, this is also known as second grade (Segundo Grado), and pupils are between 7–8 years old.
In Portugal, the second grade (segundo ano, 2º ano) is the second of the four-year 1º Ciclo do Ensino Básico that also includes the first grade, the third grade and the fourth grade.
In The Republic of Ireland, the equivalent is known as Second Class or Rang a dó (usually for 7-8 year olds) which is year 4 of Primary School. It is traditionally the year that is dedicated to preparing for the child's "First Holy Communion", however, as Ireland becomes increasingly multicultural, more and more schools are opting to prepare for the sacrement outside of school hours - at weekends or after school.
