– Elaborate on the challenges and limitations of CTT
While CTT offers numerous advantages, it is not without its challenges and limitations. One significant challenge lies in the potential for bias and unfairness in the assessment process. CTT algorithms are trained on data, and if the data contains biases, the algorithms may inherit and perpetuate these biases, leading to discriminatory outcomes.
Addressing Bias in CTT
Addressing bias in CTT requires careful consideration and proactive measures. Organizations must ensure that the data used to train CTT algorithms is diverse and representative of the population they aim to assess. Regular audits and evaluations should be conducted to identify and mitigate any potential biases.
Additionally, organizations should consider using multiple assessment methods in conjunction with CTT to reduce the risk of relying solely on algorithmic predictions. Human input and expert judgment can help balance the objectivity of CTT with the qualitative insights and contextual understanding that humans bring.
CTT Principles
CTT is based on several key principles that guide its development and application. These principles include reliability, validity, and fairness.

– Identify the strengths and limitations of CTT
CTT, or Classical Test Theory, is a psychometric framework that provides a set of principles and methods for understanding and evaluating psychological tests. It assumes that a test score is a linear combination of a true score and an error score. While CTT has been widely used in educational and psychological settings, it has both strengths and limitations that should be considered when using it.
Strengths of CTT
One of the main strengths of CTT is its simplicity. The model is relatively easy to understand and apply, making it accessible to a wide range of users. Additionally, CTT provides a number of useful statistics, such as reliability coefficients and standard errors of measurement, which can be used to evaluate the quality of a test.
Limitations of CTT
However, CTT also has a number of limitations. One of the most significant limitations is that it assumes that the relationship between the true score and the observed score is linear. This assumption is not always valid, especially when the test is not highly reliable or when the distribution of the true scores is not normal.
Another limitation of CTT is that it does not provide any information about the specific sources of error in a test. This can make it difficult to identify and correct problems with a test.
Summary of Strengths and Limitations
| Strengths | Limitations |
|---|---|
| Simplicity | Assumes linearity |
| Provides useful statistics | Does not provide information about sources of error |
