Summary:
There are three elementary schools serving grades PK through 5 in zip code 78654, all part of the Marble Falls Independent School District (Isd), which is ranked in the 38th percentile of Texas districts.
Colt Elementary is the standout school in the area, consistently ranking in the top 40-60% of Texas elementary schools with a 3-star rating, while Marble Falls Elementary and Highland Lakes Elementary rank in the bottom 30-40% with 2-star or lower ratings. Colt Elementary outperforms its peers in nearly every subject, particularly in 5th grade Reading (68.37% proficient vs. the district average of 56.44%) and 5th grade Math (56% proficient vs. the district average of 40.48%). Notably, Colt Elementary shows strong "value-add" growth, with 3rd grade Reading proficiency at 43.04% jumping to 68.37% by 5th grade, suggesting effective intervention programs. In contrast, Highland Lakes Elementary faces significant challenges with the highest free/reduced lunch rate (90.27%) and the lowest state ranking (8th percentile), despite spending the most per student ($11,368).
A key takeaway is that higher spending does not guarantee better results, as Highland Lakes Elementary spends the most but achieves the lowest scores, likely using funds to address poverty-related challenges. All three schools struggle with Math and Science compared to state averages, with 5th grade Science scores particularly low—Highland Lakes Elementary had just 7.32% proficiency in 2024-2025. Highland Lakes Elementary also shows extreme score volatility, such as 3rd grade Reading swinging from 21.74% to 70.37% between school years, indicating instability. For parents, Colt Elementary offers the strongest academic performance and upward trajectory, while the other two schools face more pronounced socioeconomic and academic hurdles.
