Abstract:
The impact of assessment results on teaching and learning development cannot 
be overstated. The performance of teachers, schools, and education systems is 
measured using test results. However there are concerns regarding 
dissatisfaction with achievement tests scores, misuse, and overuse of test 
results, high pressure to produce high test scores, high stakes nature of many 
tests uses, test scores used to determine educational improvements. The study 
assessed the perceived sources of test score pollution in Junior High Schools 
in two selected districts in the Northern Region, Ghana. A quantitative
approach using descriptive survey was used for the study thus, the use of 
questionnaires to elicit responses from selected teachers. Descriptive statistics 
(means and standard deviations) and inferential statistics (Independent 
samples t-test) were used to analyze the data. A total of 265 teachers were
sampled from the two districts (Yendi and Saboba). The findings confirmed
the main sources of test scores pollution in the districts as teacher factor, 
situational factor (test administration), and external factor (parents and 
community). The study further revealed that the incidence of test scores 
pollution was higher in private schools than the public schools. Again, test 
scores pollution was revealed to be higher in Yendi municipality than in 
Saboba district. It was recommended that government should take steps to 
reduce the high stakes nature of standardized examinations in the country and 
again provide appropriate in-service training to Junior High School teachers 
on testing practices to help curb the situation where teachers spend much time 
in class in preparing students for tests to the neglect of meaningful learning.
