Top 10 STEM and Magnet High Schools in Alaska in 2027

1. West Anchorage High School

West Anchorage ranks first because it pairs Alaska's deepest science and math magnet strands with an AP catalog exceeding 20 courses and a graduation rate near 90%. Roughly 1,700 students feed perennial robotics, Science Olympiad, and math teams that contend at state level, and magnet students routinely sit multiple AP exams before graduating. A student-teacher ratio near 18:1 funds that breadth.

It suits students who want the most complete STEM magnet in Alaska and will compete for limited strand seats that fill early. Large enrollment means bigger classes than lottery-based choice schools. Directly below it, Mat-Su Career and Technical High School trades that AP depth for a 95%-plus graduation rate and hands-on career pathways, so pick West for advanced coursework and Mat-Su for applied learning.

2. Mat-Su Career and Technical High School

Mat-Su Career and Technical High School ranks second as Alaska's best STEM value: tuition-free, lottery-admitted, and reporting a graduation rate above 95%, well ahead of the state average. About 400 students pursue engineering, health sciences, information technology, and natural-resources pathways, with dual-credit coursework through Mat-Su College and the University of Alaska letting them bank college credit before graduation.

It fits families wanting college-prep plus applied STEM without a competitive magnet test or a move to Anchorage. The trade-off is small enrollment, which limits elective and athletics breadth, and lottery demand exceeding supply. Compared with West Anchorage above it, Mat-Su gives up AP catalog depth and scale but wins on access, class size, and graduation outcomes.

3. South Anchorage High School

South Anchorage ranks third as the strongest comprehensive STEM school in Alaska, combining open enrollment with a graduation rate near 92% and an AP catalog exceeding 20 courses. Roughly 1,900 students post standout AP math and science exam results, active robotics and engineering clubs compete statewide, and the modern campus supports well-equipped science labs. Four-year college enrollment runs high, with strong UA and Pacific Northwest matriculation.

It suits families who want elite AP results without a magnet application. The trade-offs are larger STEM class sizes and no selective strand for the most advanced students. Against Mat-Su Career and Technical above it, South offers far more AP breadth but lacks guaranteed dual-credit career pathways and the 95%-plus graduation rate.

4. Service High School

Service High School ranks fourth for hosting the Anchorage district's International Baccalaureate program, a structured pathway where roughly 1,800 students take higher-level math, physics, and chemistry. The graduation rate sits near 88%, AP offerings run broad alongside the IB diploma track, and science-fair participation ranks among the strongest in the district.

It suits globally minded students ready for the demanding IB diploma rather than a standard AP sequence. The trade-offs: IB is not a fit for every student, and running AP and IB tracks side by side can split resources. Compared with South Anchorage above it, Service offers the IB credential but a lower graduation rate and no open-enrollment magnet breadth.

5. Juneau-Douglas High School: Yadaa.at Kalé

Juneau-Douglas High School: Yadaa.at Kalé ranks fifth as Southeast Alaska's strongest STEM school, enrolling roughly 1,000 students with a graduation rate near 87%. Its AP catalog covers calculus, biology, chemistry, and computer science, dual-credit ties run to the University of Alaska Southeast, and marine science and field-based environmental coursework exploit the capital's coastal setting. Robotics teams compete at state level.

It suits Southeast families who want college credit and coastal science without leaving the region. Smaller enrollment limits advanced course sections, and the isolated location restricts competition travel. Against Service High School above it, Juneau-Douglas trades IB rigor and scale for marine fieldwork and a tighter, place-based STEM program.

6. Eagle River High School

Eagle River High School ranks sixth on the strength of a graduation rate near 91%, one of the higher figures in the Anchorage district. About 1,000 students access a respectable AP slate in math and science, active STEM clubs, and regional robotics and science events, all supported by small-community engagement and strong teacher-student relationships.

It suits families north of Anchorage who want solid AP STEM close to home rather than a commute to midtown magnets. The trade-offs are fewer advanced electives than the largest Anchorage schools and a smaller competition program. Compared with Juneau-Douglas above it, Eagle River offers a higher graduation rate but less dual-credit structure and no marine science focus.

7. Colony High School

Colony High School ranks seventh as the Mat-Su Valley's best comprehensive STEM school, enrolling roughly 1,300 students in Palmer with a graduation rate near 90%. It pairs AP math and science courses with dual-credit pathways through Mat-Su College, and its agriculture and natural-resources programs add an applied STEM dimension uncommon elsewhere in Alaska. Valley community support runs strong.

It suits Mat-Su families wanting AP plus college credit without an Anchorage commute. The AP catalog is narrower than the Anchorage magnets, and rapid valley growth strains class sizes. Compared with Eagle River High School above it, Colony offers dual credit and applied science but a slightly lower graduation rate and larger, faster-growing classes.

8. Dimond High School

Dimond High School ranks eighth as a dependable large-school STEM choice in south Anchorage, enrolling about 1,900 students with a graduation rate near 89%. Its broad AP program sees strong math and science participation, robotics and engineering clubs stay active, and its size funds a wide elective slate and well-staffed science departments. Graduates feed steadily into the UA system and out-of-state colleges.

It suits Anchorage families who want AP breadth and club options under open enrollment. The trade-offs are bigger class sizes and no selective magnet strand for top students. Compared with Colony High School above it, Dimond offers a wider AP catalog and larger scale but lacks Colony's dual-credit pathways and agriculture programs.

9. Thunder Mountain High School

Thunder Mountain High School ranks ninth for pairing a modern Juneau campus with well-equipped science and technology labs. Roughly 700 students post a graduation rate near 86%, access AP math and science, and use dual-credit partnerships with the University of Alaska Southeast. Smaller size supports close mentorship and active regional science and robotics competition.

It suits Juneau families wanting a modern, mentorship-driven STEM option alongside the larger Juneau-Douglas campus. Smaller enrollment limits advanced course sections, and recent consolidation discussions create planning uncertainty. Compared with Dimond High School above it, Thunder Mountain trades scale and AP breadth for lab facilities and tighter student-teacher relationships.

10. Kodiak High School

Kodiak High School ranks tenth as Alaska's standout rural and island STEM school, enrolling about 700 students with a graduation rate near 88%. It offers AP math and science alongside marine biology and fisheries science coursework tied directly to the island's fishing economy, plus dual-credit ties to Kodiak College and active robotics participation for a rural school.

It suits island and rural families who want STEM with real-world marine relevance close to home. The remote location limits competition travel, and smaller enrollment narrows the AP catalog. Compared with Thunder Mountain High School above it, Kodiak offers a stronger marine science identity but fewer lab resources and a slightly lower graduation rate.

How we ranked these

Rankings were built from publicly reported data on six weighted factors: STEM programming depth such as AP and dual-credit coursework (25%), college and post-graduation outcomes (20%), value and access including tuition and admission method (15%), teachers and resources (15%), school environment and safety (15%), and STEM competitions and extracurriculars (10%). Sources included U.S. News, Niche, GreatSchools, the College Board, and Alaska DEED figures.

Deliberately excluded: single-test scores, athletics, and reputation-driven prestige, because they distort STEM fit and favor large Anchorage schools. We also ignored marketing claims and unverified self-reported outcomes. Small rural schools were judged on program depth relative to their size, not raw course counts, since geography and enrollment make a deep catalog genuinely harder to build in Alaska.

What to look for

Between these schools, the real differentiators are admission method, program depth in your specific STEM interest, and commute reality. West and Service run selective magnet or IB strands; Mat-Su CTHS admits by lottery; South, Dimond, Colony, and Eagle River serve zoned families. A student who thrives in a 1,900-student AP environment may struggle in a 400-student project-based school, and vice versa.

The mistake most buyers make is chasing the top-ranked name without checking whether the magnet strand has open seats, whether dual-credit courses transfer to the intended university, and whether the daily travel is sustainable for four years. In Alaska, weather, distance, and lottery timing decide more outcomes than a one-spot ranking difference ever will.
