Summary

Lewis (William C.) Dual Language Elementary School is a public elementary school in Wilmington, Delaware, serving 316 students in grades K-5. The school is part of the Red Clay Consolidated School District, which is ranked 12th out of 32 districts in the state and has a 3-star rating from SchoolDigger.

Despite the school's dual language focus, Lewis (William C.) Dual Language Elementary has consistently underperformed compared to the district and state averages on Smarter Balanced Assessments for English Language Arts and Mathematics. For example, in the 2024-2025 school year, the school's proficiency rates were significantly lower than the district and state in 3rd, 4th, and 5th grade ELA and Mathematics. The school also has high chronic absenteeism rates, ranging from 18.6% to 23.5% over the past few years, which is much higher than the district and state averages.

When comparing Lewis (William C.) Dual Language Elementary to nearby schools within the same Red Clay Consolidated School District, the performance gap is even more pronounced. Schools like Shortlidge (Evan G.) Academy, Warner Elementary School, and Johnson (Joseph E. Junior) Elementary School all have significantly lower proficiency rates in ELA and Mathematics compared to the district and state averages as well. Addressing the root causes of these performance gaps, such as chronic absenteeism, will be crucial for the school to improve student outcomes.

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
