Lewis (William C.) Dual Language Elementary School

Public Grades K-5

95^th

SchoolDigger Rank ?

of 107 Delaware Elementary Schools

Better than 11% of Delaware elementary schools

Summary

Lewis (William C.) Dual Language Elementary School is a K-5 public school in Wilmington, DE, serving 347 students within the Red Clay Consolidated School District.

Lewis stands out for its dual-language immersion program, which is showing real promise for its English Language Learner (ELL) students. In fact, the school's ELL subgroup has made remarkable strides, jumping from the 7th percentile statewide in 2018-2019 to the 45th percentile in 2024-2025. This suggests the program is increasingly effective at serving its core mission. The school also maintains a notably low student-teacher ratio of 11.9:1, which is better than nearby Johnson (Joseph E. Junior) Elementary School (13.1:1) and Kuumba Academy Charter School (13.2:1), allowing for more personalized attention. However, overall academic performance remains a challenge. The school ranks in the bottom quartile of Delaware elementary schools, and there is a significant achievement gap when compared to First State Montessori Academy, located less than a mile away, where proficiency rates in subjects like 5th-grade ELA are more than double Lewis's rates.

Another area of concern is a widening gender gap. While female students rank in the 27th percentile, male students have dropped to the 8th percentile, indicating a critical need for targeted support for boys. On a more positive note, Lewis's chronic absenteeism rate of 22.4% is significantly better than its Red Clay neighbors, Warner Elementary School (39.5%) and Shortlidge (Evan G.) Academy (36.3%), suggesting the school is more successful at getting students to class. The school is also well-funded, spending over $18,000 per student, which indicates resources are available; the challenge lies in translating that investment into stronger academic results across all student groups.

My son began kindergarten at Lewis last year. I was trying to choice him into North Star in Hockessin before I visited Lewis, but the cold reception I received from the North Star teachers and staff prompted me to give Lewis a chance. I am so glad I did! My son has been made to feel like he was a wanted member of the Lewis family since Day One. Additionally, I feel he is getting a really good education so far. He can already read in English and Spanish and is above his age level in math. The teachers and students are welcoming and caring. I have nothing but wonderful things to say about this school. Furthermore, Lewis just received an award for top school in the United States from the Spanish embassy. I think I made the right choice for my son. I look forward to his first-grade experience at this great city school. Close Quote

My daughter attends William C. Lewis Elementary, and is at present in the 1st grade. I think it is an excellent school. With a very large Hispanic population, of course, the DCAS scores will be lower. Some of the Hispanic children that enter William C. Lewis, speak very little English. So, when given a test in English their test scores will certainly be lower. My daughter is an African American. She started at Lewis in the Kindergarten grades. She is so far quite literate as a beginner with her Spanish skills. By her learning two languages she is showing adept skills in her verbal and reasoning abilities. She is learning at a very young impressionable age that there are different cultures and languages in the world other than just English. I think because of William C. Lewis' unique dual language curriculum that they should be measured in a different manner than just DCAS scores. Especially when you are talking about a school's ranking. Close Quote
