Science and math achievement scores of 3rd, 4th, and 5th grade elementary students were studied using a sample of 196 students from McAuliffe Elementary School, located in McAllen, Texas. Students in the experimental group participated in the Junior Master Gardener™ program in addition to the traditional classroom-based math and science methods. In contrast, students within the control group were taught math and science using only traditional classroom-based methods. No statistically significant differences were found in comparisons of science students' achievement scores, indicating that those students using the Junior Master Gardener™ program as a method to learn science benefited similarly to those who learned using only traditional science classroom-based instruction. However, results indicated statistically significant differences in comparisons of students' math achievement scores showing that those students who received traditional math instruction had more improved math achievement scores compared to those taught using the Junior Master Gardener™ program. Results also found no statistically significant differences between demographic groups indicating that males and females and students from different ethnicities benefited similarly from participation in the Junior Master Gardener™ program.
