The principal building, the Hall of Great Accomplishment, stands 15.5 metres high, 19.7 metres wide and 17.6 metres deep. Built to a five-bay layout, it adopts the nine-ridge hip-and-gable hall roof form. The interior is luxuriously decorated. The three main roof beams retain well-preserved folk-style Central Plains polychrome paintings. Eight front pillars support the eaves; each measures 1.85 metres in girth and 4.6 metres in height. The four front pillars are fully carved with deep relief coiled dragons, capped with fanged tiger heads gazing down at the dragons, depicting a lively scene of tigers and dragons frolicking together. The octagonal plinths under the pillars feature relief carvings. The two central plinths bear illustrations of the River Diagram and Luo Shu writing on their front faces, while the others depict auspicious motifs: carps leaping over the Dragon Gate, high-ranking officials at court, nobles receiving official seals and other good-luck stories with delicate workmanship.

The wooden brackets are decorated with openwork carvings on brackets, arms, cantilevers, rafters and spandrels. The upper tier of the bracket heads features colourful dragon heads, while the middle and lower tiers take the shape of elephant trunks, complemented by openwork carvings of rolling clouds and waves. The horizontal beams beneath the brackets are painted with auspicious dragons soaring among clouds.

Directly behind the Hall of Great Accomplishment stand the Hall of Moral Cultivation, the Classics Repository, as well as rockeries and gardens in sequence. Along the eastern axis are the Memorial Archway for Chaste Widows, the Shrine for Chaste Women, the Shrine for Sage Ancestors, the Confucian Academy and the rear gate. The western axis includes the Shrine of Loyalty and Righteousness and the Earth God Shrine. Outside the Sage Domain Gate and Worthy Gate stand the Dragon Soaring Archway and the Phoenix Ascending Archway respectively. Adjacent to the academy gate is the Wenkui Tower Courtyard. Also known as the Eight Trigrams Pavilion, Kuixing Tower or Kuige Pavilion, the tower was first constructed in the sixth year of the Wanli reign of the Ming Dynasty (1579) and reconstructed in the twenty-fourth year of the Qianlong reign of the Qing Dynasty (1759). Rising 14 metres high, it has a gilded pyramidal roof with a rounded ridge topped by a two-metre-tall pagoda-shaped treasure vase. Dragon heads sit at the end of each of the eight roof ridges, linked to the roof top by eight iron chains. The two-storey octagonal tower has wind chimes hung on each upturned corner.

The eastern, central and western axes together with the Wenkui Tower Courtyard form a complete, rigorously structured layout that fully absorbs the combined architectural features of the Confucius Temple and Kong Family Mansion in Qufu.

Leading architectural heritage experts have spoken highly of this temple. Luo Zhewen, a specialist in ancient architecture from the State Administration of Cultural Heritage, commented: "The Jiaxian Confucian Temple remains largely intact. It used to be an imperial academy and a landmark of history. The carved dragon pillars are extremely rare, magnificent and of great cultural value." Zheng Xiaoxie, Chairman of the National Committee for the Protection of Historical and Cultural Cities, praised the exquisite carvings on the brackets and wooden pillars. Thanks to its grand momentum, refined craftsmanship, elegant structural design, peerless wood carvings and outstanding painted decorations, Jiaxian Confucian Temple is reputed as a temple built to "imperial palace standards".
