FreshmanA freshman, fresher, first year, or colloquially frosh, is a person in the first year at an educational institution, usually a secondary school or at the college and university level, but also in other forms of post-secondary educational institutions. In much of the Arab world, a first-year is called a "Ebtidae" (Pl. Mubtadeen), which is Arabic for "beginner". In Brazil, students that pass the vestibulares and begin studying in a college or university are called "calouros" or more informally "bixos" ("bixetes" for girls), an alternate spelling of "bicho", which means "animal" (although commonly used to refer to bugs).
Junior (education year)A junior is a person in the third year at an educational institution in the US and some other countries, usually at a secondary school or at the college and university level, but also in other forms of post-secondary educational institutions. In United States high schools, a junior is an eleventh-grade student; juniors are considered upperclassmen. In the United States, the 11th grade is usually the third year of a student's high school period and is referred to as junior year.
Senior (education)The term senior, in regard to education, has different meanings depending on the country. In the United States education, a senior is a student in the fourth year of study, either in high school or college/university. The twelfth grade is the fourth and final year of a student's high school education. The year and the student are both referred to as senior. The fourth year of an undergraduate program is known as senior year, and 4th year students are known as seniors. Bachelor's degree programs are designed to be completed in four years.
Secondary schoolA secondary school or a high school describes an institution that provides secondary education and also usually includes the building where this takes place. Some secondary schools provide both lower secondary education (ages 11 to 14) and upper secondary education (ages 14 to 18), i.e., both levels 2 and 3 of the ISCED scale, but these can also be provided in separate schools. In the US, most local secondary education systems have separate middle schools and high schools.
