Summary:
Zip code 36541 in Grand Bay, Alabama, is served by two public elementary schools—Breitling Elementary School and Cora Castlen Elementary—both part of the Mobile County district and both serving grades PK-5 with similar enrollments of roughly 420-470 students.
For parents, the standout choice is Cora Castlen Elementary, which has earned a 4-star rating for three straight years and ranks in the 72nd-74th percentile statewide. Its most impressive achievement is a remarkable 87.88% proficiency rate in 3rd grade English—more than 23 points above the state average—and it also posts strong 5th grade English (82.09%) and 4th grade science (65.67%) scores. Notably, Cora Castlen achieves these results with a higher student-teacher ratio (19.2:1) and lower per-student spending ($9,872) than its neighbor, suggesting instructional quality drives its success. Breitling Elementary School has improved from a 2-star to a 3-star rating and shows a dramatic one-year jump in 4th grade science (from 41.76% to 62.50%), but it still trails Cora Castlen in most subjects. The only area where Breitling leads is 5th grade math (44.94% vs. 41.79%), a potential weakness for Cora Castlen.
Both schools outperform their district averages in nearly every subject and grade, making them relative bright spots within Mobile County, which ranks in only the 33rd percentile statewide. Chronic absenteeism is a modest concern at both schools (12.9% at Breitling, 10.6% at Cora Castlen), slightly above the state average. Cora Castlen also shows a distinctive "V-shaped" pattern in English scores—strong in 3rd grade, dipping in 4th, then recovering in 5th—which may reflect curriculum transitions. Overall, Cora Castlen offers the stronger educational option for families, though Breitling is showing promising improvement trends.
