在過去的二十年裡，赫特伍德的A-Level 成績使赫特伍德成為「全國最好的學校之一」（英國《金融時報》），在男女混合寄宿學校排行榜上名列前茅，始終領先於大多數著名的寄宿學校。
這些輝煌的成果是不言而喻的，它們在數學、科學、經濟學、現代語言、歷史和英語等核心學科領域的成就與創意學科的成就一樣多。
潛在的科學家、語言學家、藝術家、哲學家、律師、演員或工業領袖——每個人都得到很好的照顧，每個人都受到同等的重視。 Hurtwood 為學生準備 22 門 A-level 科目，這些科目可以任意組合學習。這使學生能夠選擇一個能夠反映他們個人優勢和熱情的課程，並讓他們邁出實現夢想之旅的第一步。所有 A Level 課程都是完全線性的，並在兩年課程結束時進行考試。
目前有超過150 名學生正在學習數學或科學作為他們的A-level 科目之一，赫特伍德學生在頂尖大學獲得的名額反映了從化學工程和醫學到應用心理學和法律的真正多樣化的職業抱負。
For the last two decades, the A-level results have put Hurtwood “among the cream of the country’s best schools,” (Financial Times) at the top of the League Table for co-ed boarding schools, consistently ahead of most of its illustrious rivals.
These brilliant results speak for themselves, and they are achieved as much in core academic subjects such as Mathematics, Science, Economics, Modern Languages, History and English, as they are the creative ones.
The potential scientist, linguist, artist, philosopher, lawyer, actor or captain of industry – each is well catered for and each is equally valued. Hurtwood prepares students in 22 A-level subjects which can be studied in any combination. This enables students to select a programme which reflects their personal strengths and passions and puts them on the first step of the journey towards the realisation of their aspirations. All A Level courses are fully linear and are examined at the end of the two-year course.
More than 150 students are currently studying Mathematics or Science as one of their A-level subjects, and the places which Hurtwood Students have been awarded at the top universities reflect a real diversity of career aspirations, from Chemical Engineering and Medicine to Applied Psychology and Law.
