Advanced AET Admissions Guide for 10th Graders

Advanced AET is not the same application eighth graders complete for ninth grade AOS or AET entry. It sits in the winter admissions cycle for current high school students, and LCPS has historically described it as a two-year pathway that students apply to during 10th grade for entry in 11th grade.

The most important word in that sentence is historically. Families can use the prior cycle to understand the shape of the process, but they should not copy old deadlines or prerequisites into a new calendar. As of July 16, 2026, the central LCPS admissions page has not posted the next Advanced AET dates and criteria.

The short version

Confirm that Advanced AET is the right winter pathway, keep the student's score reports and academic record organized, and wait for the active LCPS packet before treating any prerequisite or deadline as final. January 16, 2026 was the previous deadline, not the next one.

What Advanced AET is, and why the application is different

The official AET program page describes engineering and information-technology study built around research, design, and advanced coursework. Advanced AET provides a later entry point than the four-year AET pathway that begins in ninth grade.

That later entry point changes the application context. The fall AOS and AET process is for current eighth graders. The current LCPS admissions FAQ places Advanced AET and MATA applicants in the winter cycle for current high school students. A family searching for “the ACL application” can easily land on the wrong cycle unless it checks the program name and applicant grade first.

Official fact versus prior-cycle context

LCPS currently confirms that Advanced AET is part of winter admissions. Detailed course prerequisites and the next deadline must come from the active winter materials. Older LCPS pages can explain what happened before, but they cannot set the next cycle's rules.

What LCPS currently confirms

Even before the next packet appears, the official FAQ gives families a useful boundary:

Winter admissions serve current ninth, 10th, and 11th grade applicants across the eligible Advanced AET and MATA options.
Applicants must live in Loudoun County and, if admitted, remain full-time students at both their home high school and the Academies of Loudoun.
Winter applicants without a PSAT score report may submit an SAT or ACT score report by the published deadline.
Students may participate in only one ACL curricular program at a time.

Those are current FAQ statements. They do not tell us the next Advanced AET opening date, closing date, pathway-specific prerequisites, or assessment schedule.

What is not yet published for the next cycle

An official LCPS high school course-selection page records January 16, 2026 at noon as the Advanced AET and MATA application deadline for the previous cycle. That date has passed. It should appear in a family's notes only as historical context.

As of this guide's fact-check date, the central admissions page does not publish the next winter deadline or a complete next-cycle Advanced AET criteria sheet. That means we will not fill the gap with an assumed November opening, a repeated January deadline, or a copied course list from a prior year.

When the new materials appear, verify all of the following directly:

which current grades may apply to each Advanced AET pathway;
the required math and science courses, including any exclusions;
which grades and score reports are reviewed;
whether a writing assessment is required and when it occurs;
the application, accommodation, and document deadlines.

What a 10th grade family can do now

AcademiesPrep interpretation

The planning sequence below is our guidance, not an LCPS admissions formula. It is designed to keep a family ready without pretending the unpublished cycle is already known.

1. Start with program fit

Advanced AET is a substantial academic commitment, not simply a second chance at the ninth grade AET application. Read the program description, look at the kind of research and design work students do, and ask whether the pathway matches how the student wants to spend half of the school week.

2. Build a clean academic snapshot

Keep the student's current schedule, completed math and science courses, and available score reports in one place. Do not self-screen from an old checklist. Once the active criteria are published, compare the official wording with the student's actual transcript and ask the school counselor about anything ambiguous.

3. Protect access to score reports

The current FAQ allows an SAT or ACT report when a winter applicant does not have a PSAT report. Make sure the family can retrieve the relevant report before the deadline. A valid score sitting in an inaccessible account is an avoidable last-minute problem.

4. Prepare only for a confirmed assessment

If the active packet includes a writing assessment, practice should focus on planning, developing, and revising a clear response under the published time limit. Our winter small-group coaching is designed around the active Advanced AET cycle, so its calendar and emphasis should follow the official packet rather than guess ahead of it.

The mature move here is not to do nothing. It is to separate work that remains useful in any cycle from work that depends on rules LCPS has not yet announced.

Advanced AET Admissions Guide FAQs

When do students apply to Advanced AET?

Advanced AET belongs to the winter admissions cycle for current high school students. LCPS materials have described it as an option students apply to during 10th grade for entry in 11th grade. Families should confirm the grade and pathway rules in the active cycle packet.

Is January 16, 2026 the next Advanced AET deadline?

No. January 16, 2026 was the published deadline for the previous winter cycle and has passed. As of July 16, 2026, LCPS has not published the next Advanced AET deadline on its central admissions page.

Can an applicant use the SAT or ACT instead of the PSAT?

The current LCPS admissions FAQ says winter applicants without a PSAT score report may submit an SAT or ACT score report by the published deadline. The active cycle instructions will control the exact submission process.

Should a family rely on last cycle's course prerequisites?

No. Prior criteria are useful context, but they are not a promise for the next cycle. Confirm course, grade, testing, and pathway requirements when LCPS publishes the active winter materials.
