Mrs McCabe believed that subject rigour, depth of subject knowledge and the ability to communicate a love of subject to students are the fundamental requirements for effective teaching.
She had a passion for art and literature, and was responsible for building the Performing Arts Centre in 2007, which now hosts over 50 productions and concerts each year, and enables every girl to participate in performances.
Mrs McCabe is Co-Director of the Princes Teaching Institute, and together with her NLCS teaching staff, has shared a commitment to subject based learning with over 1000 maintained schools and 3300 teachers. She served on a number of governing bodies and national education committees in the maintained and independent sectors, including the National Grammar Schools Association and the GSA/HMC Universities Committee. Since 2010 she has been a member of the Government's National Curriculum Review Advisory Committee and was named in the Evening Standard's Top 1000 Most Influential People in London.
Mrs McCabe encouraged students to be outward-looking and internationally minded, and set up overseas NLCS branches in Jeju and Dubai. Mrs McCabe is now NLCS Director of International Schools and Education Strategy.
