我國自1982年（民國71年）開始自全國中小學科學展覽會選派學生代表參與國際科學競賽，並於1991年（民國80年）起開始單獨辦理「中華民國參加國際科學展覽活動」國內選拔賽，選拔優秀學生參與多國國際科學展覽會，代表同學於國外表現成績也很優異。2002年（民國91年）鑒於受邀參與之各國代表隊增多，包含美國、加拿大、香港、新加坡、紐西蘭、泰國、南非、墨西哥、德國、法國、俄羅斯、西班牙及匈牙利等國，參加件數也逐年增加，因此經由教育部召開科學展覽設計指導委員會，綜合各方意見將活動辦理更名為「臺灣國際科學展覽會」。

臺灣國際科學展覽會每年都有約20多個來自歐、亞、美、非等洲之各國代表學生以優秀科學作品與國內中學生進行科學研究成果交流，而選拔之代表學生在國際賽事也表現相當亮眼。

以2019年我國參加於美國亞利桑那州鳳凰城舉行之英特爾國際科技展覽會(Intel ISEF)為例，在這個素有「中學生科學奧林匹亞競賽」之稱的國際科學賽事中，2019年共有82個國家/地區，1842名學生，1,454件作品參賽，我國13名學生10件作品在眾多競爭者中脫穎而出，囊括7項大會獎、4項特別獎，展現豐碩成果，2021年疫情期間，改為線上參與，也有佳績，顯示我國中等學校科學教育基礎紮實，讓參賽代表在國際舞臺上能發光發亮。

我國參與美國國際科技展覽會(ISEF)40年來，共選派學生323人次、260件作品參賽，其中得獎學生達209人次，得獎作品有168件，包括1項英特爾青年科學家獎（Intel Young Scientist Award）、4項大會歐洲參訪研習獎、12項科首獎、137項大會獎（Grand Award）及138項特別獎（Special Award），成果相當豐碩。

2022年國際科展國內共有521位學生，276件作品在去年12月報名，其中有254位學生，137作品通過初審進入複審，連同國外作品，本次展覽會共有582位師生，來自23個國家，179件作品進入決賽。

臺灣國際科學展覽會活動摘述如下：

• 國內作品由學校推薦報名後先參加臺灣初審；選拔後再與受邀國家之區域或全國性比賽中之優勝作品共同參加國際科學展覽會競賽。
• 展覽科別分數學、物理與天文學、化學、地球與環境科學、動物學、植物學、微生物學、生物化學、醫學與健康、工程學、電腦科學與資訊工程、環境工程及行為與社會科學科等13科。
• 參展對象含國內學生及國外學生兩大類；國內外學生均可以個人作品或團隊（2~3人）作品參賽。
• 國內作品獎勵辦法：
  一等獎、二等獎、三等獎及四等獎作品，頒發所屬學校、教師及學生獎狀、獎金或獎牌，另自一、二、三等獎作品中選拔優秀作品代表我國參加各國際科學展覽活動。成績優異學生，輔導進入研究機構繼續專題研究工作，使其成為未來之科學人才。
• 展覽會期間舉辦開幕典禮暨創意座談、教師交流會、學生交流會、公開展覽及科教設施參觀等活動，並由我國師生及外國師生共同參與，增加國內外師生觀摩交流機會。
• 結合青少年科學人才培育，接洽大專院校、科學研究機構相關專長之教授支援，提供優勝學生繼續研究之環境及所需要之輔導。

In order to establish the roots of science education in Taiwan and expand the international vision of our secondary school students, the National Taiwan Science Education Center (hereinafter referred to as "NTSEC") has been organizing the "Taiwan International Science Fair" since 1991. TISF has been separated from the National Primary and High School Science Fair to select student representatives for the international science exhibitions.

To increase the opportunities of international science education exchange and observation for our teachers and students, we have invited more teams from the Pan-Pacific region to participate in the event, and since then, the number of foreign projects and countries participating in the event has increased year by year.

The TISF is identified by the Ministry of Education (MOE) of Taiwan and the TISF guideline is formulated by the Science Fair Consult Commission. The judging procedure includes D&S review, three-stage interview and the award categories are Young Scientist Award, the First to Fourth award and Special Awards which refer to the ISEF and is a rigorous science fair.

A total of 521 students and 276 projects were submitted for the preliminary round of the 2022 TISF in December last year, and 254 students and 137 projects were selected for the final round of the competition. A total of 582 students and teachers from 23 countries and 179 winning works will enter the final round of the competition.

At the same time, in order to broaden the horizons of our students' scientific research and to strengthen international science education exchanges, the NTSEC will hold a series of activities during the Taiwan International Science Fair 2021, such as the opening ceremony and keynote speech, student-teacher workshops, and public exhibition, to achieve the purpose of academic and cultural exchanges through the participation of teachers and students.

Each year, after the TISF, the National Taiwan Science Education Center selects the best students to represent Taiwan to participate in international science fairs in the United States, ESI, Tunisia, Turkey and Brazil, etc. They have performed well. However, our team participated in I-Fest2 in Tunisia, MOSTRATEC in Brazil, and BUCA IMSEF in Turkey, and won gold, silver, and bronze medals, as well as first and third prizes.

Although the ISEF in the U.S. was not held in 2020 due to the pandemic, our team participated in I-Fest2 in Tunisia, MOSTRATEC in Brazil, and BUCA IMSEF in Turkey. They had won many awards, including gold, silver, and bronze prizes. The Taiwan student team's accomplishments were very impressive and evident to all.

In order to let the students who are representing Taiwan nationally concentrate on science research without any worries, MOE issues the “Regulations Governing Academic Advancement Incentives for Students with Great Performance in International Mathematics or Science Olympiads and International Science Fairs” so that the talented young scientists can have the recommendations for admission to higher education.

The Ministry of Education (MOE) has promulgated the "Regulations Governing Academic Advancement Incentives for Students with Great Performance in International Mathematics or Science Olympiads and International Science Fairs" to enable students with excellent performance in international science fairs to be guaranteed admission, recommended for admission to universities, or to study abroad at public expense, so as to nurture more outstanding scientific talents for the country.
