This article explores the issue of improving pedagogical mechanisms in assessing speaking and writing skills in English. The study is based on the theoretical approaches proposed by O’Sullivan (2012) and Weigle (2012) and analyzes ways to enhance the reliability, validity, and practical effectiveness of the assessment process. In assessing speaking, factors such as task design, interlocutor influence, test-taker’s personal characteristics, and assessor subjectivity are considered significant. Moreover, diversifying task formats — including interviews, monologues, role plays, and group discussions — is emphasized as an effective means to comprehensively demonstrate learners’ communicative competence. Regular training and calibration of assessors are also highlighted as essential for ensuring consistency and objectivity in scoring. In writing assessment, maintaining a balance between grammar accuracy, vocabulary richness, and logical organization of ideas is of great importance. Analytical rating scales, such as the FSI model, allow for more detailed identification of learners’ strengths and weaknesses. Furthermore, ensuring fairness in the assessment process — through gender and age balance among interlocutors and equal testing conditions — guarantees the validity and reliability of test results. In conclusion, the article acknowledges that the implementation of modern pedagogical mechanisms in assessing speaking and writing skills plays a crucial role in improving the overall quality of language teaching.
