Does it matter when you go off to boarding school? What is the most common point of entry? Are there any advantages to entering 9th grade versus entering 10th grade? What about attending boarding school just for 11th grade or 12th grade? Does that make sense? Is it even possible? The answers to these questions depend on you and your circumstances.
10th Grade Entry and Academics
The most common entry point for American college prep boarding schools has traditionally been 10th grade. That makes sense for many students because college preparatory studies usually cover a three-year cycle. Many schools offer the Advanced Placement, or AP program. AP courses allow high school students to pursue college-level studies. The AP courses vary from school to school, so be sure to scrutinize the academic curricula carefully as you search for the right boarding school for your child. While many boarding schools offer a wide range of AP subjects, some frequently offer highly specialized courses that are difficult to find in many other schools.
10th grade is also a sensible entry point at boarding schools that offer the IB or International Baccalaureate programme. The IB programme has many programme-specific features. The IB Diploma Programme itself is designed for students aged 16 to 19 and is typically implemented during the final two years of secondary education, so families should check the individual school's curriculum and preparation requirements.
