Abstract:
Performance in Mathematics in Meru County, Kenya from 2012 to 2016 has consistently 
been deteriorating. The purpose of this study was to examine the effects of how the
administrative strategies designed by the principals on students‟ Mathematics performance in
the Kenya Certificate of Secondary Education (KCSE) in Meru County. Objectives that 
directed the study were to examine the effects of various attributes on students‟ performance 
in the KCSE examination in Meru County. The objectives were to examine the effects of the 
Principal‟s invitation of Mathematics specialists, establish Principals‟ support to teachers 
through Mathematics seminars, and determine the effects of principals‟ organization of 
Mathematics contests and evaluate the effects of Principals‟ provision of materials for 
learning and teaching. This study used ex post fact research design because of the effects of
independent variables on dependent variables. The research instrument was a Mathematics
teachers‟ questionnaire and the Principal‟s interview guide. The target population was 299
principals and 836 Mathematics teachers in the County. This study used stratified random 
sampling with proportional allocation. The sample size was 30% of the total target population 
translating to 92 principals and 251 Mathematics teachers. Validity was insured by piloting 
the instrument. Reliability was insured by using the split-half technique. From the findings, 
the majority ofMathematics teachers and principals claimed that they invited Mathematics 
specialists and used team teaching and peer teaching specialists to their schools. However,
most of the invitations were done only once a year. Chi-square results showed that the 
invitation of Mathematics specialists (p 0.021), team teaching (p 0.0065), peer teaching 
specialists (p 0.048), and others (p 0.034) all had a significant effect on how students 
performed. Findings further revealed that principals were not sponsoring Mathematics 
teachers to attend seminars with the majority having never attended Mathematics contests in 
the last two years. The principals cited a lack of resources and budgetary allocation to the low 
number of Mathematics teachers attending seminars. It was also revealed that most principals 
did not organize Mathematics contests, and the majority of schools never organized 
Mathematics contests. The ANOVA results showed a significant association between the 
mean performance in Mathematics and the number of Mathematics contests organized by the 
principals (p=0.000<0.05). In regards to teaching resources, the majority of schools had 
satisfactory Mathematics syllabus provision, adequate departmental teaching and revision 
materials, and adequate textbooks. However, marking and checking schemes of work were 
not satisfactory to the majority of the respondents. In regards to learning resources, the 
majority of respondents affirmed that teaching aids were satisfactorily provided, but schools 
were not financially stable, which was evidenced by the low organization of Mathematics 
contests externally as compared to high organizations internally. The study recommends that
principals should invite more than one Mathematics specialist to their schools to ensure that 
Mathematics teachers and students are adequately exposed to different kinds of skills and 
strategies on Mathematics performance in the K.C.S.E examination. Principals should also
increase the frequency of inviting the external support staff from annually to one or twice per 
term to ensure that the skills and strategies imparted are reinforced to become a routine 
practice for the mathematics teachers and the students. The findings of the study were
expected to be useful to the Ministry of Education, teachers, and students as well as other 
stakeholders in the education sector. The researchers also concluded that attendance of 
seminars was minimal or non-existent in the majority of the schools, it was also concluded 
that schools in Meru County did not generally organize external Mathematics contests. The 
study also concluded that the provision of teaching and learning resources affected school 
performance in mathematics.
