Academies of Loudoun Admissions by the Numbers

Every applicant and admission count LCPS has published for AOS, AET, and MATA, taken from School Board documents, with what the numbers can and cannot tell you.

The Short Version

AET, fall 2020
1,650 applied and 145 were admitted, about 8.8%.
AOS, fall 2020
1,689 applied and 122 were admitted, about 7.2%.
MATA, 2024
2,239 applied, 1,041 were offered a seat, and 836 accepted.
AOS and AET after 2020
LCPS has not published applicant or admission counts for AOS or AET since the 2020 presentation.

Every count on this page is copied from a Loudoun County School Board document, linked under Sources. The percentages are our own arithmetic from those counts.

AOS and AET: Fall 2020

These are the most recent AOS and AET applicant counts LCPS has published. They come from a presentation to the School Board on August 11, 2020, and describe the students admitted for fall 2020, the last class chosen before the 2020 changes to the process.

AOS and AET applicants and admitted students, fall 2020
Program Applied Admitted Share admitted
AET 1,650 145 8.8%
AOS 1,689 122 7.2%

Applied and admitted are the totals of the two groups LCPS reported by economic status, below. Share admitted is admitted divided by applied.

By economic status

AOS and AET applicants and admitted students by economic status, fall 2020
Group Applied Admitted
AET, economically disadvantaged 196 3
AET, not economically disadvantaged 1,454 142
AOS, economically disadvantaged 228 3
AOS, not economically disadvantaged 1,461 119

Three students from economically disadvantaged families were admitted to each academy that year. That gap is one of the reasons LCPS gave for changing the process in 2020.

By Middle School, Fall 2020

LCPS compared the number of students each middle school sent to AOS and AET with the number it would expect from that school’s share of 8th grade enrollment. The last column marks the schools where enrollment was under 75% of that expected number, as LCPS flagged them.

AOS and AET students enrolled and expected by middle school, fall 2020
Middle school AOS enrolled AOS expected AET enrolled AET expected Under 75% of expected
Belmont Ridge 6 7 Not listed Not listed
Blue Ridge 1 5 6 6 AOS
Brambleton 15 8 11 10
Eagle Ridge 13 8 18 9
Farmwell Station 10 7 8 9
Harmony 2 7 3 8 AOS, AET
Harper Park 3 7 9 8 AOS
J. Lupton Simpson 0 7 6 9 AOS, AET
J. Michael Lunsford 13 10 Not listed Not listed
River Bend 1 7 6 9 AOS, AET
Seneca Ridge 1 6 4 7 AOS, AET
Smart's Mill 1 7 6 8 AOS
Sterling 0 7 3 8 AOS, AET
Stone Hill 15 6 22 8
Trailside 10 8 7 9
Willard 31 14 14 16

Enrollment is as of May 2020. Mercer Middle School is not included because it had no 8th grade class that year. The AET tables have no rows for Belmont Ridge or J. Michael Lunsford, so the AET column adds up to less than the 145 admitted. LCPS reported 8 middle schools under 75% for AOS, with 9 students between them, and 5 for AET, with 22.

MATA: 2019 to 2024

LCPS reported MATA applications, offers, and acceptances for six years in its 2024-25 MATA report to the School Board. Applications nearly doubled over that time while offers grew much less, so the share of applicants offered a seat fell.

MATA applied, offered, and accepted, 2019 to 2024
Year Applied Offered Accepted Share offered
2019 1,257 886 717 70.5%
2020 1,360 917 725 67.4%
2021 1,332 919 786 69.0%
2022 1,950 1,020 804 52.3%
2023 2,165 1,061 856 49.0%
2024 2,239 1,041 836 46.5%

Years are as LCPS labels them. Share offered is offered divided by applied. MATA students choose up to three pathways, and LCPS does not break these totals down by pathway.

How AOS and AET Selection Worked Under the 2020 Policy

In August 2020, LCPS staff told the School Board how AOS and AET students would be chosen starting that fall. In plain terms:

  1. Eligibility. 8th graders in or past Algebra I, with a C average or better in grades 6 and 7. Today’s requirement is narrower: a C or higher in specific math and science courses.
  2. Two assessments on one day. Every eligible applicant takes a STEM Thinking Skills Assessment and a Writing Assessment.
  3. A profile for each applicant. The Research Office builds a profile from the two scores.
  4. A panel review, school by school. A panel of educators gets the profiles ranked by STEM test score within each middle school, and separately for students from economically disadvantaged families, with the writing score alongside.
  5. A floor, not a quota. The panel’s list must include at least 75% of each middle school’s expected share, and of the expected share of economically disadvantaged students. LCPS’s example: a school expected to send 8 students gets at least 6 recommended, with a wait list behind them.

LCPS has not said publicly whether this process still applies. Its admissions page today says only that applicants are evaluated on all of the published criteria, with no benchmarks or minimum scores.

Is It a Lottery?

Not for AOS or AET. Families sometimes hear that AOS and AET admission is a random lottery. Nothing LCPS has published says so. Applicants take the Writing Assessment and the admission test, and LCPS says they are evaluated on all of the published criteria.

MATA is different. LCPS checks each applicant’s requirements, then holds a lottery only when more qualified students apply than there are seats.

What LCPS Has Not Published

AOS and AET counts after 2020
No applicant, offer, or admission counts for AOS or AET have appeared in School Board documents or on LCPS pages since the 2020 presentation.
Admission test scores
LCPS mails each applicant their own scores but publishes no score scale, averages, or cutoffs, and says there is no minimum score.
Advanced AET
No applicant or admission counts are published.

Any AOS or AET acceptance rate you see for a recent year is an estimate, not an LCPS figure.

ACL Admissions Data: Common Questions

What is the Academies of Loudoun acceptance rate?

The latest published figures are for fall 2020: 145 of 1,650 AET applicants were admitted, about 8.8%, and 122 of 1,689 AOS applicants, about 7.2%. LCPS has not published AOS or AET counts since then.

How many students apply to MATA?

LCPS reported 2,239 MATA applicants in 2024, with 1,041 offered a seat and 836 accepting. Applications have grown each year since 2021.

Is AOS and AET admission a lottery?

No. Applicants take the Writing Assessment and the admission test, and LCPS says they are evaluated on all of the published criteria. Only MATA uses a lottery, and only when more qualified students apply than there are seats.

Does my middle school affect my child’s chances?

The 2020 policy had a panel review applicants ranked within each middle school and recommend at least 75% of each school’s expected share. LCPS has not said whether that rule still applies.

Is there a minimum test score?

No. LCPS says there are no benchmarks or minimum scores, and that applicants are evaluated on all of the published admissions criteria.

Where do these numbers come from?

From two School Board documents: an August 11, 2020 presentation on AOS and AET admissions, and the 2024-25 MATA report. Both are linked under Sources.

Sources, last checked September 26, 2026
