John B. Sliney School has consistently ranked in the top half of Connecticut elementary schools, with a ranking between 152-266 out of 500+ schools over the past 10 years. The school's performance on SBAC English Language Arts and Mathematics assessments is generally above the state average, with 3rd and 4th-grade proficiency rates often exceeding 50%. The school also performs particularly well for its Special Education and Low Socioeconomic Status student subgroups, ranking in the top 25-30% of Connecticut elementary schools for these groups.
