Addenbrooke Classical Grammar School

Summary:

Addenbrooke Classical Grammar School is a public charter elementary school serving grades PK-8 in Lakewood, Colorado, part of the Jefferson County School District, which is ranked 35 out of 116 districts in the state and has a 4-star rating. Addenbrooke has seen a decline in its student racial diversity over the past few years, with the percentage of white students increasing from 71.17% in 2020-2021 to 65.52% in 2022-2023.

Addenbrooke's academic performance, as measured by CMAS test scores, is generally higher than the district and state averages, particularly in English Language Arts, with 46.6% of its students proficient or better in 2023-2024 compared to 51.8% for the district and 44.1% for the state. The school's statewide ranking fluctuates between the top 20-50% of Colorado elementary schools, and its rating has varied from 2 to 4 stars out of 5 on the SchoolDigger scale. Addenbrooke's Hispanic students and male students perform particularly well compared to their peers statewide, often ranking in the top 20-30% of Colorado elementary schools in those subgroups.

When compared to the surrounding schools, such as Westgate Elementary and Kaiser Elementary, Addenbrooke generally outperforms them academically, particularly in ELA and Math. However, the school's lack of recent socioeconomic data and the growing racial homogeneity of its student body are areas that warrant further exploration and consideration.

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.

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.
