English plays a central role in the CSS examination in Pakistan. It is not only a compulsory subject but also the primary medium of communication in other papers, especially the Essay and Précis & Composition papers. Proficiency in English reflects a candidate’s analytical and communicative ability—both of which are essential for public service roles.

Strong command over grammar, vocabulary, comprehension, and writing structure is critical. Candidates are also expected to present complex arguments clearly and concisely, which is why regular writing practice and reading quality English material—like newspapers, journals, and books—is essential.

A lack of English proficiency is one of the top reasons for failure in CSS, making it a subject of utmost importance in any preparation strategy.
