More dramatically, Lassiter’s scores are nearly double those of nearby Sprayberry High School and Wheeler High School, which post Algebra I proficiency rates of just 41.8% and 41.5%.

Beyond test scores, Lassiter boasts a 97.3% graduation rate—10 points above the state average—and a dropout rate of just 0.5%. Chronic absenteeism (11.3%) is also well below the district (14.2%) and state (17.7%) averages, and less than half the rate seen at Wheeler (22.7%) or Sprayberry (20.7%). Interestingly, Lassiter achieves these results while spending $13,092 per student, which is actually less than several lower-performing nearby schools. The school’s consistent top-20 state ranking over the past decade, coupled with its strong performance for special education students and its efficiency, makes it a standout choice for families seeking a high-achieving, well-rounded high school experience in the East Cobb area.
