End of Grade


Mountain Discovery EOG Results

As required by the state of North Carolina, Mountain Discovery administers End of Grade testing to 3rd through 8th grades in Math and English Language Arts. In addition, 5th and 8th graders take a Science EOG. Middle school students enrolled in Math 1 also take a state required End of Course test. All tests are administered at the end of the year in the state determined testing window. MDCS uses the test results as one of the many data points to measure student growth and grade level proficiency. Individual results are made available to parents as soon as the state allows.

The tables below present testing results from the past 5 years. Hover over the column headings if you don’t understand the terms or to get more details on the data. A small window should pop up with more information.

Our generally outstanding test results are validation that making learning fun, engaging, and relevant for our children gives them the tools they need to succeed in the world at large. Although I can’t prove it, I believe that the results also reflect our attention to every student’s social, emotional, and physical well being. If you want to learn more about the educational experience that lies behind our excellent performance on tests, visit our director’s page for a guided tour of our website.

At the very least, visit the Meet Our Staff page to learn something about the amazing people behind our success. As an administrator, I am honored to work with such a talented and dedicated staff. As a parent of two MDCS alumni, I can personally attest to the wonderful results of an MDCS education and I am blessed that it was an option for my children.

MDCS PC: The percentage of state tests on which MDCS students scored at a Level 3 (proficient at grade level) or higher. PC = Performance Composite

State PC: The percentage of state tests on which North Carolina students scored at a Level 3 (proficient at grade level) or higher. PC = Performance Composite

Diff: Number of percentage points by which MDCS outperformed statewide results (Col.2- Col.3).

Growth: Target EOG scores are calculated for each student based on the preceding year’s score. If a student meets or exceeds his/her individual target scores s/he has met growth expectations. A school meets growth expectations if about 50% of students meet their individual targets on a test. A school achieves high growth status if at least 60% of students meet their individual target scores.

%ile: The percentage of North Carolina K-8 schools that MDCS outperfomed on a given test or tests.

SPG: School Performance Grade in accordance with the new state rating system implemented in 2014. For additional information, use the links at the bottom of the page.

*FERPA regulations prevent us from reporting exact percentages if they are over 95%.
