As you review the school rankings data, please be aware that some of the information from certain demographics is missing. The reason for this omission is that the data has been redacted from the source data itself due to low population samples in these specific demographic groups.

Redacting data from low population samples is a necessary step to ensure the reliability and accuracy of the results, as small sample sizes may not be representative of the broader population. Additionally, this measure helps protect the privacy of individuals belonging to these demographic groups.

My son graduated this past year and my daughter is a sophmore. I can't say enough about how great this school is. My son was very well prepared for college and had an amazing array of outside opportunities which only added to his college prep resume. He also had a lot of fun in high school with all-school hikes, wilderness field trips and other fun group activities. Even kids that aren't that into nature and ecology can benefit from the school's ecological focus. My son didn't take that many "ecology" type course work and he wasn't pressured to do so. He took a very traditional set of high school classes and did very well due to the excellent instruction he received. There are fewer AP's offered than you will find at a large school but the ones that you do take are very well taught and supported so if you study hard you will do well on the AP exams which is what matters most about AP's. My daughter is a current Sophmore and is very challenged by her coursework. She's found a very nice group of friends and because the school is quite small can get help from teachers anytime she feels she needs it. My son was literally accepted into 12 colleges! And I expect the same thing will happen for my daughter. If you are serious about college for your child I highly recommend CG. Not only will your child get a great high school education they will have a wonderful experience as well. What more could one ask for from a high school? Close Quote

About Students eligible for discounted/free lunch:

The National School Lunch Program (NSLP) provides low-cost or free meals to students in U.S. public and nonprofit private schools based on household income. Those with incomes below 130% of the poverty line receive free lunch, while those between 130% and 185% qualify for reduced-price lunch. The percentage of students receiving free or reduced-price lunch serves as a marker for poverty, as it reflects the socioeconomic status of families in a given school or district. A higher FRPL rate typically indicates a higher concentration of low-income families, suggesting that the school or district may face additional challenges in providing adequate resources and support for student success.

About Student-Teacher Ratio

Student/teacher ratio is calculated by dividing the total number of students by the total number of full-time equivalent teachers. Please note that a smaller student/teacher ratio does not necessarily translate to smaller class size. In some instances, schools hire teachers part time, and some teachers are hired for specialized instruction with very small class sizes. These and other factors contribute to the student/teacher ratio. Note: For private schools, Student/teacher ratio may not include Pre-Kindergarten.
