BACKGROUND OF THE STUDY
In the realm of education, the proficiency in the English language stands as a pivotal factor influencing students' academic success. The mastery of English not only facilitates communication but also serves as a gateway to accessing knowledge across various disciplines. In the context of post-primary schools, where students undergo crucial stages of cognitive and intellectual development, the relationship between performance in English language and overall academic achievement becomes particularly significant. This paper aims to explore the intricate interplay between English language proficiency and the academic performance of students in post-primary schools, drawing insights from empirical research and theoretical frameworks.
English has emerged as a global lingua franca, fostering cross-cultural communication, economic mobility, and access to information. In the educational landscape, proficiency in English is closely linked to academic achievement and future prospects. According to Cummins (1981), proficiency in the language serves as a cognitive tool that enables students to comprehend complex concepts, engage critically with academic materials, and express their ideas effectively. Additionally, English proficiency is often a prerequisite for higher education opportunities, employment prospects, and participation in the global economy (Chavez & Torres, 2018). Thus, understanding the dynamics of English language proficiency among post-primary school students is essential for enhancing educational outcomes and fostering socio-economic development.
The relationship between English language proficiency and academic performance can be understood through various theoretical lenses. One such framework is the Linguistic Interdependence Hypothesis proposed by Cummins (1979), which posits that proficiency in one's first language (L1) can positively influence the acquisition of a second language (L2) and overall academic achievement. According to this hypothesis, the cognitive and linguistic skills developed in the first language serve as a foundation for learning additional languages, including English. Conversely, the Threshold Hypothesis (Cummins, 2000) suggests that there is a certain level of proficiency in English beyond which students begin to experience significant academic benefits. These theoretical frameworks provide valuable insights into the complex relationship between language proficiency and academic achievement among students in post-primary schools.
Numerous empirical studies have investigated the relationship between English language proficiency and academic performance among post-primary school students. For instance, a longitudinal study conducted by Baker et al. (2008) examined the English language development and academic progress of bilingual students in post-primary schools. The findings revealed a positive correlation between English proficiency levels and academic achievement across various subjects. Similarly, a meta-analysis conducted by August & Shanahan (2006) synthesized findings from multiple studies and concluded that students with
