Summary

Union Grove High in McDonough, GA, serves about 1,622 students in grades 9-12 within the Henry County School District, and it stands out as a strong, 4-star performer in a district that overall earns just 2 stars.

For parents, the most encouraging news is that Union Grove consistently beats both district and state averages in key areas. In the latest testing cycle, the school posted a 53.4% proficiency rate in Biology—well above the state average of 47.2% and far ahead of the district's 36.5%. U.S. History proficiency (49.8%) also tops state (38.5%) and district (33.3%) averages. The school's graduation rate is a stellar 94.3%, and its dropout rate is just 0.8%, about one-third of the state rate. Perhaps most impressive is the chronic absenteeism rate of only 9.7%—less than half the district rate (19.6%) and dramatically lower than nearby schools like Stockbridge High School (38.6%) and Heritage High School (37.8%). Even Ola High School, the only nearby school with comparable academics, has a higher absenteeism rate (16.9%).

Union Grove's main academic challenge is Algebra I, where proficiency (34.6%) trails the state average (48.1%). This is a notable contrast with Ola High, which posts a 60.7% Algebra I proficiency rate. However, Union Grove edges out Ola in U.S. History (49.8% vs. 45.9%) and nearly matches it in Biology. The school also shows strong results with African American students, who rank in the 79th percentile statewide—its best subgroup performance. While Union Grove hasn't quite returned to its pre-pandemic peak ranking, it remains a reliable, efficient choice: it spends less per student ($12,504) than Ola ($13,032) or Woodland High School ($13,439) while achieving far better outcomes than the latter. For families seeking a high-engagement, high-graduation school with strong science and history programs, Union Grove is a compelling option.

What people are saying

by a student
Wednesday, June 1, 2022

As a student at Union Grove, I can say that my overall experience at the school is below par. This is not an extensive list of everything that’s going on at this school, just a list of things that occurred. To give a little background information, me and my family moved to this school because it had a high rating. We were not expecting to encounter so many unprofessional staff members at school. Assistant principals and even the principal don’t respond to emails when they’re busy. The teachers aren’t better at that. I was trying to figure out the situation with one of my grades, my parents wanted to schedule a meeting. No meeting was scheduled and I went to the counseling office to try and figure out the situation. When I came to the office, the staff called in the assistant principal. She began yelling at me, I was trying to explain the situation, and she began talking over me. I then called my guardian so the assistant principal could go talk to her and she started yelling, talking over her, and saying “mom we’re not gonna go back and forth”. In my view, she was trying to explain the situation to her but she wasn’t willing to listen. She also told her that she will always be on the side of teachers. This is not everything that transpired in the five minutes she entered the office to communicate with us, and we didn’t get the situation solved. When you’re absent for some time, some teachers don’t want to help. My technology teacher wouldn’t let me fix a mistake she got a student to help me because she was busy. She didn’t grade from the rubric and took points off for things she didn’t like. It appears to me that UG just wants their students to pass. This is not only our opinion but what several other students and parents have told us. I had several situations where I needed something resolved and the staff wasn’t willing to help, this is one example. Close Quote
