"The Impact of Student Demographics on National
Achievement Test Scores" `
Introduction
1.1 Background of the Study
In recent years, educational institutions have increasingly relied on
standardized testing to measure student achievement and overall school
performance. One such assessment is the National Achievement Test (NAT),
which serves as a critical indicator of educational outcomes across various
regions. Despite its widespread use, significant disparities in NAT scores have
been observed, raising concerns about the underlying factors contributing to
these differences.
1.2 Statement of the Problem
While numerous studies have explored the general factors affecting
academic performance, there is a lack of comprehensive research specifically
examining
the
impact
of
student
demographics
on
NAT
scores.
Understanding how factors such as age, gender, family income, and parental
education influence these scores is crucial for developing targeted
interventions to improve educational equity and student outcomes.
1.3 Research Objectives
This study aims to investigate the following objectives:
1.
2.
3.
4.
To identify the relationship between students' ages and NAT scores.
To determine the impact of gender on NAT scores.
To analyze the influence of family income levels on NAT scores.
To examine the effect of parents' educational backgrounds on NAT scores.
1.4 Research Questions
This study seeks to answer the following research questions:
1.
2.
3.
How does the age of students relate to their NAT scores?
What is the impact of gender on NAT scores?
How do family income levels affect NAT scores?
4.
What is the influence of parents' educational backgrounds on NAT scores?
1.5 Significance of the Study
Understanding the impact of student demographics on NAT scores is vital for
policymakers, educators, and stakeholders. By identifying key demographic
factors that influence academic performance, targeted interventions can be
designed to support underperforming groups and bridge achievement gaps.
This study will contribute to the body of knowledge on educational equity
and provide practical recommendations for improving NAT outcomes.
1.6 Scope and Delimitations
This study focuses on students from a selection of schools that participate in
the National Achievement Test. It will collect and analyze data on student
demographics,
including
age,
gender,
family
income,
and
parents'
educational backgrounds. The study is limited to quantitative data and will
not explore qualitative aspects such as students' attitudes or teachers'
perceptions.
Chapter 2: Review of Related Literature and Theoretical Framework
2.1 Introduction
This chapter reviews the existing literature on the impact of student
demographics on academic performance, particularly focusing on National
Achievement Test (NAT) scores. It discusses relevant theories, including
learning theories, and presents a conceptual framework for the study,
distinguishing between dependent and independent variables.
2.2 Relevant Theories
2.2.1 Socioeconomic Status and Education
Socioeconomic status (SES) is a significant predictor of educational
outcomes. Research has consistently shown that students from higher SES
backgrounds tend to perform better academically. This can be attributed to
several factors, including access to resources, parental involvement, and
educational opportunities.
2.2.2 Learning Theories
Behaviorist Theory: According to behaviorist theories (Skinner, 1953),
learning is a result of conditioning, where behavior is shaped by
reinforcement or punishment. In the context of academic performance,
students who receive positive reinforcement for their achievements are more
likely to perform well on standardized tests like the NAT.
Cognitive Development Theory: Piaget ’ s (1964) theory of cognitive
development suggests that students' ability to understand and perform on
tests is related to their developmental stage. Age, as a factor, plays a crucial
role in determining students' cognitive abilities and, consequently, their
performance on the NAT.
Sociocultural Theory: Vygotsky (1978) emphasized the importance of social
interactions and cultural context in learning. He proposed that learning
occurs through social interaction and that children ’ s development is
influenced by their cultural environment. This theory underscores the role of
parental education and involvement in shaping students' academic outcomes.
Constructivist Theory: Bruner (1966) suggested that learning is an active
process where learners construct new ideas based on their current and past
knowledge. This theory highlights the importance of a supportive learning
environment and access to educational resources, which are often correlated
with family income levels.
2.3 Related Literature
2.3.1 Age and Academic Performance
Studies have shown a correlation between age and academic performance.
Younger students in the same grade level often perform differently
compared to their older peers due to differences in cognitive and emotional
development. Research by Bedard and Dhuey (2006) indicates that older
students within a grade cohort tend to have higher academic achievement,
which could be reflected in NAT scores.
2.3.2 Gender and Academic Performance
Gender differences in academic performance have been widely studied.
According to a meta-analysis by Voyer and Voyer (2014), female students
often outperform male students in language and reading, while male
students tend to perform better in mathematics. These differences can
impact NAT scores, depending on the subjects tested.
2.3.3 Family Income and Academic Performance
The relationship between family income and academic performance is welldocumented. Research by Duncan and Magnuson (2011) demonstrates that
higher family income is associated with better educational outcomes. This is
attributed to factors such as access to educational resources, extracurricular
activities, and a conducive learning environment at home.
2.3.4 Parental Education and Academic Performance
Parental education level is a strong predictor of students' academic success.
According to Davis-Kean (2005), parents with higher educational attainment
are more likely to engage in practices that promote their children's academic
achievement, such as reading to them and providing a stimulating home
environment.
2.4 Conceptual Framework
The conceptual framework for this study is based on the premise that
student demographics, including age, gender, family income, and parental
education, influence NAT scores. In this framework, the independent
variables are the demographic factors, and the dependent variable is the
NAT score.
Independent Variables:
1.
Age: The age of students may influence their cognitive and
emotional development, affecting NAT scores.
2.
Gender: Gender may lead to differences in performance in various
subjects tested in the NAT.
3.
Family Income: Higher family income can provide better educational
resources and support, influencing NAT scores.
4.
Parental Education: Higher levels of parental education are
associated with practices that support academic achievement, thereby
affecting NAT scores.
Dependent Variable: 12460
1.
NAT Scores: The scores obtained by students in the National
Achievement Test.
HYPOTHESIS
Based on the conceptual framework and existing literature, the following
hypotheses are proposed:
Hypothesis 1 (Age): Older students will achieve higher NAT scores compared
to younger students.
Hypothesis 2 (Gender): Female students will achieve higher NAT
scores in language and reading sections, while male students will
achieve higher scores in mathematics and science sections.
Hypothesis 3 (Family Income): Students from higher-income families
will achieve higher NAT scores compared to students from lowerincome families.
Hypothesis 4 (Parental Education): Students whose parents have
higher levels of education will achieve higher NAT scores compared to
students whose parents have lower levels of education.
Null Hypotheses
In addition to the hypotheses above, the null hypotheses are as follows:
Null Hypothesis 1 (Age): There is no significant difference in NAT
scores between older and younger students.
Null Hypothesis 2 (Gender): There is no significant difference in NAT
scores between male and female students in different subject areas.
Null Hypothesis 3 (Family Income): There is no significant difference in
NAT scores between students from different family income levels.
Null Hypothesis 4 (Parental Education): There is no significant
difference in NAT scores between students with parents of different
educational backgrounds
Definition of Terms

Chapter 3: Research Methodology
3.1 Introduction
This chapter outlines the methodology employed to investigate the impact of
student demographics on National Achievement Test (NAT) scores. It
describes the research design, data collection methods, and statistical
analysis techniques used to achieve the study objectives.
3.2 Research Design
This study adopts a quantitative research design to systematically examine
the relationship between student demographics and NAT scores. A crosssectional approach is employed, where data is collected at a single point in
time from a diverse sample of students across different schools participating
in the NAT.
3.3 Participants
The participants in this study consist of students from various educational
institutions that administer the NAT. Sampling is conducted using a stratified
random sampling technique to ensure representation across different
demographic groups based on age, gender, family income, and parental
education levels.
3.4 RESEARCH INSTRUMENT
The primary research instrument for data collection is a structured
questionnaire distributed to students and their families, aimed at gathering
information on demographic factors. These include recording age in years to
determine its influence on NAT scores, categorizing gender into male and
female to analyze gender-based performance differences, collecting family
income using predefined income brackets to assess its impact on academic
achievement, and capturing parental education by asking about the highest
educational attainment of both parents to understand its correlation with
NAT scores.
3.4 Data Collection
Data collection involves gathering information on student demographics and
NAT scores from school records and administrative databases. Demographic
data includes age, gender, family income, and parental education, which are
obtained through structured questionnaires or surveys distributed to
students and their families.
3.5 Variables and Instruments
Independent Variables: Age, gender, family income, and parental education.
Dependent Variable: NAT scores obtained by students in subjects assessed
by the test.
3.6 Data Analysis
Statistical analysis includes descriptive statistics to summarize demographic
characteristics and NAT scores. Correlation analysis, using Pearson
correlation coefficients, examines the relationships between independent
variables (age, gender, family income, parental education) and the
dependent variable (NAT scores). Multiple regression analysis will be
employed to assess the combined effect of these variables on NAT scores
while controlling for potential confounding factors.
3.7 Ethical Considerations
Ethical approval is obtained from relevant institutional review boards to
ensure the protection of participants' rights and confidentiality of collected
data. Informed consent is obtained from students and their parents or
guardians before participation in the study.
