Construct validity is a way to estimate the correlations and their extents. It has further types, including convergent and divergent validity in assessment. If you are stuck between these concepts of measurement, then you must learn about the facts connected with them. In this regard, the current article can help you as it aims to discuss the unfold facts of convergent and divergent validity in assessment.

What is Convergent Validity in Assessment?

Convergent validity in assessment is the way to evaluate the construct that correlates the selected tests with each other. In this method, it is estimated that one test has the same construct as the other one. You can construct one test with other based on several aspects, including the procedure of test. Other than tests, there can be the same construct of results based on the need of the hour. Now, you have to see what kind of assessment is present between tests. Also, you can identify the strength of validity to get the best end results. The purpose of all the discussed steps is to determine the way to prove its validity. Furthermore, you can better identify the thing to measure in the test.

Let’s Understand it With the Help of an Example.

Suppose, a class of intermediate. The main aim of measurement is to check the validity of math results. The class is subjected to perform their best in mathematics. In order to assess the convergent validity, you need to see how much similarity is there between the test results of the whole class. If the class has close results, it means the validity is positive as well as strong. On the other hand, if the results are not close to each other and there is a large difference, it means the correlation is not strong but weak.

What is Divergent Validity in Assessment?


Divergent validity in assessment is also known as discriminant validity. The purpose of divergent validity is to evaluate the differences existing between selected tests. Most of the time, this validity correlation is selected to use when differences are expected to occur between tests. At the time of assessment, you can select one aspect of the test for measurement or there can be multiple aspects as well. In divergent validity, you have to see how much discrimination is there and based on the assessment results; you can use correlation in further studies.

Let’s understand this correlation with the help of an example.

Suppose, there is a class of matriculation. Here, your aim is to create a divergent correlation between the two subjects of English and mathematics. These are two different subjects which can have a high possibility of generating a high divergent correlation. The rate of difference in results determines the strength of validity.

What are the Five Unfold Facts Related to Convergent and Divergent Validity in Assessment?

There are so many facts relevant to convergent and divergent validity in assessment. Before using these methods, it is necessary to know about the facts, so you can better generate good end results for study. Both of the validities are very close to each other. It would not be wrong to say that these two validity methods are two facets of a similar coin. Following are facts that can provide strength to your task performance:

  • Construct Validity 

Both convergent and divergent validity in assessment are subtypes of validity type, which is named as construct validity. The purpose of both validities is different, but both of them fall under the same umbrella. By having a clear understanding of its main course, you can collect the best information in no time. Also, you would not have to spend a long time in research. Furthermore, you can better come up with relevant case studies. There can be some case studies which have used both of correlations. So, you need to identify that what is the purpose behind your study and then search for similar aspects.

  • Comparison of Results

In convergent and divergent validity in assessment, you are supposed to compare the results of a particular test. The main course is to focus on results, but the rest of procedure also plays a significant role. For example, convergent validity highlights similar studies. If you select two different studies, there will be a zero correlation in the result, which is of no use. If you find the same zero correlation between similar studies, it would be a useful result.

In contrast, the comparison of results for divergent validity is of no use if it is made between similar subjects, but they are supposed to be conducted for two opposite constructs.

  • Strength of Correlation

The strength of correlation is an advanced step that is conducted after finding the nature of correlation. For example, you have generated a convergent correlation between two scientific constructs.

  • First of all, you have to see if there is a positive or zero correlation existing between the selected constructs.
  • Secondly, you have to estimate if the positive relation is strong or weak.

The same steps are followed by divergent correlation.

  • Evaluation of Validity 

The evaluation of convergent as well as divergent validity can be made at the same time. It does not mean, you cannot use these validity correlations separately, but you can better identify the effective results by having both correlations of scientific methods.

  • Threats to Validity 

Both correlations have the same threats to validity which include the failure of exhaustive and selective. In order to avoid these threats in your task, you can get the assistance of experts working at services similar to dissertation writing services

Final Thoughts 

The above-mentioned pointers are the basic facts of which most of students are not aware. That is how different concepts become the cause of confusion, and you may get daunting results. By understanding the mentioned facts, you can grasp the problem, and it becomes easy to proceed further.
