ABSTRACT 
This study was carried out to investigate peer group influence and academic performance of public secondary school students in Port Harcourt Metropolis. The study was specifically carried out to determine the relationship between behavioural peer group influence and academic performance of students in public secondary schools in Port Harcourt Metropolis, examine the relationship between academic peer group influence and academic performance of students in public secondary schools in Port Harcourt Metropolis, ascertain the relationship between social peer group influence and academic performance of students in public secondary schools in Port Harcourt Metropolis and find out the relationship between emotional peer group influence and academic performance of students in public secondary schools in Port Harcourt Metropolis. The study employed the descriptive research design. The population of the study comprised 3,200 students in public secondary schools in Port Harcourt Metropolis. A sample size of 356 respondents was determined using Taro Yamane formula, while 341 validated copies of questionnaire were used for the analysis. The study adopted a multi-stage sampling technique involving stratified and convenience sampling methods. Hence, the questionnaire was used for data collection, while the data collected were analyzed using mean and standard deviation. The hypotheses were tested using Analysis of Variance statistical tool at 0.05 level of significance. From the responses obtained and analyzed, the findings revealed that behavioural peer group influence has a significant relationship with academic performance of students in public secondary schools in Port Harcourt Metropolis at F = 5.721, P = 0.001. The study also showed that academic peer group influence has a significant relationship with academic performance of students at F = 6.384, P = 0.000. Likewise, the study further revealed that social peer group influence has a significant relationship with academic performance of students at F = 5.283, P = 0.002. The findings additionally indicated that emotional peer group influence has a significant relationship with academic performance of students at F = 5.967, P = 0.001. The study therefore recommends that school administrators and teachers should encourage the formation of academically oriented peer groups that promote positive study habits and academic commitment among students.

INTRODUCTION (Preview)
1.1 Background of the Study
Success in academic performance in formal education systems has been linked for a long time to a multitude of interacting behavioural and environmental factors, not just cognitive. Adolescent educational participation is often determined by interpersonal relations, institutional structures and socio-cultural norms that interact and affect learning pathways. Brouwer et al. (2022) argue that peer relations developed in learning communities play a large role in differences in academic outcomes, as they are continually reproduced in the form of interactional patterns. Likewise, Jeptoo and Edabu (2022) noted that peer factors are still important in influencing pupils' learning achievements at various educational levels. In the field of peer relations, Lorijn et al. (2024) also highlighted the importance of transitions for academic progress as measurable shifts in peer relations and academic progress often occur simultaneously. Besides, Burgers (2026) reported that peers have a high influence on behavioural and academic orientations of learners in educational contexts. The observations as a whole illustrate that peer-related variables are part of larger educational systems, and thus suggest a starting point for exploring different aspects of peer influence in formal school settings.
Behavioural peer group influence is one of the most noticeable aspects that impact student involvement in learning processes, especially in secondary school settings where young people are most vulnerable to peer group dynamics. Omolekan and Ajayi (2023) found that there is a significant relationship between behavioural peer pressure and discipline and academic involvement of secondary school students. Likewise, Mordi and Onoyase (2023) found peer induced behavioural tendencies as one of the factors that accounted for the differences in academic performance of senior secondary school students. Peers' classroom behaviour which may support or hinder academic focus may also influence instructional outcomes (Ajayi et al., 2023). Concurrently, Adewuyi (2024) found that peer behaviour patterns such as social media usage and peer conformity can predict academic performance outcomes. In addition, Shaukat and Hussain (2024) reiterated the fact that peer group relationship plays a significant role in the behavioural adjustment in academic environments. Together, these behavioural dimensions form a pathway that can lead to patterns of academic performance among students based on their peer interactions.
Academic peer group influence is another important aspect through which learners can impact each other's academic performance through collaboration, tutoring and academic motivation. Peer teaching strategies have proven to be effective in improving students' academic performance in structured learning environments like anatomy classes, as reported by Chiegeiro et al. (2025). Likewise, Adika and Toyobo (2026) found that peer academic interaction is highly related to students' achievement and learning interest. The study by Eleje et al. (2025) also showed that peer mentorship programmes can have a positive impact on the academic performance of underperforming learners by providing them with structured support systems. In addition, Ajayi et al. (2023) also reported that peer-assisted instructional approaches are beneficial for science achievement of secondary school students. Lorentzen (2025) further pointed out how peer academic networks can affect the progression of performance over time, as a result of ongoing academic exchange. Together, these findings provide evidence of the influence of academic peers through cooperative learning and how this can impact achievement in a variety of subject areas.
Social and emotional peer group influences are more complex and subtle but nonetheless important aspects of student academic outcomes because they affect motivation, emotional regulation and interpersonal adjustment in the school context. The combined impact of peer pressure and emotional intelligence on academic performance and social media use among adolescents was identified by Isyaku et al. (2025). Similarly, Okafor et al. (2026) found that peer group dynamic has a significant impact on student's academic performance when there is a social interaction pattern. Social peer networks are closely related to the interest in school and continued engagement in schoolwork (Adika and Toyobo, 2026). Adewuyi (2024) also noted that peer social network use is a factor of academic variability. These behavioural, academic, social, and emotional peer dimensions converge in the Nigerian educational context, especially in urban secondary schools like those in Port Harcourt Metropolis, offering a structured framework for analyzing their interrelationships with academic performance, as evidenced in the findings by Omolekan and Ajayi (2023), Isyaku et al. (2025), and Okafor et al. (2026).

1.2 Statement of the Problem
The school context has become more complex and interpersonal relations in secondary schools are no longer confined to the formal teaching-learning process. Peer-related interactions now play a significant role in students' learning experiences, transcending behaviour, learning engagement styles, social affiliation and emotional attachments. Peer associations are multidimensional; they have measurable impact on school outcomes of students through behavioural modelling and social reinforcement mechanism, according to Adewuyi (2024). Likewise, Lorijn et al. (2024) found that differences in academic career paths are related to changes and persistence in peer networks. Although there is an increasing awareness of these influences, empirical understandings of the specific relationship between different dimensions of peer influences and academic performance of secondary school students in specific urban school context like Port Harcourt Metropolis are still not clear.
Current educational observations show that students tend to emulate behaviours they see within their peer groups, which can sometimes result in increased engagement in learning and sometimes in decreased engagement in learning. Omolekan and Ajayi (2023) revealed that peer pressure is one of the significant correlates of student behaviour and academic outcome while Mordi and Onoyase (2023) attributed peer influence to emotional and psychological factors influencing performance. However, the specific effect of peer influence on behaviour on academic outcomes among public secondary school students is not consistently found in the literature. Burgers (2026) also noted that peer dynamics are strong predictors of adolescent behavior, but that empirical assessments are still scarce in various school settings, and that there is a lack of localized evidence.
Further, academic peer group influence (collaborative learning, peer tutoring, and shared academic motivation) is found to have a positive impact on educational achievement in some contexts. According to Ajayi et al., (2023) and Chiegeiro et al., (2025), structured peer learning interventions are effective in enhancing academic performances in science related subjects. However, results have been mixed as to whether informal academic peer interactions have similar effects in public secondary schools. Peer mentorship is effective in enhancing the performance of underachieving students, limited quantifiable evidence has been found in the context of general student population in Port Harcourt (Eleje et al., 2025). This discrepancy suggests that academic peer influence as a measurable predictor of academic performance should be further explored. Moreover, the social and emotional peer influences remain a significant determinant of students' engagement in school and learning outcomes. Isyaku et al. (2025) pointed out that social engagement and peer pressure collectively contribute to academic performance, and Shaukat and Hussain (2024) reported that peer relationships have a significant impact on school performance. Emotional peer influence, such as acceptance, belongingness and interpersonal attachment, has also been found to be linked to learning motivation and achievement rates (Lorentzen, 2025). Although these connections have been identified, there is a dearth of studies that look at the behavioural, academic, social and emotional peer group influences simultaneously in the public secondary schools of Port Harcourt Metropolis. This lack of empirical evidence highlights the need for the current study to establish the relationship between these dimensions and academic performance in the specific educational setting.
