The Scottish education system has always been different from the rest of the United Kingdom, with a characteristic emphasis on a broad education. Scotland's schools operate a Curriculum(课程) for Excellence which provides knowledge and skills to all nursery, primary and secondary schooling between the ages of 3 - 18. All 3- and 4-year-old children in Scotland have access to a free nursery place. Formal primary education begins at approximately 5 years old and lasts for 7 years. During their secondary education, children in Scotland study Standard Grades, or Intermediate(中级的) qualifications between the ages of 13 and 16 . The school leaving age is 16, after which students may choose to remain at school for one or two years to study for Higher Grade or Advanced Higher qualifications. Then they can have further education by attending colleges or universities.

There are fifteen Scottish universities, some of which are among the oldest in the world. These include the University of St Andrews, the University of Glasgow, the University of Aberdeen and the University of Edinburgh—many of which are ranked among the best in the UK. Proportionally, Scotland had more universities in QS' World University Rankings' top 100 in 2012 than any other nation. Also, the country produced 1% of the world's published research with less than 0.1% of the world's population. Scotland’s University Courts are the only bodies in Scotland authorized to award degrees.

Besides Scotland's universities, Further and Higher Education is provided by 43 colleges as well. Colleges offer National Certificates, Higher National Certificates, and Higher National Diplomas. These Group Awards, alongside Scottish Vocational（职业的） Qualifications, aim to ensure Scotland's population has the appropriate skills and knowledge to meet workplace needs. In 2014, research reported by the Office for National Statistics found that Scotland was the most highly educated country in Europe and among the most well-educated in the world in terms of higher education attainment.
