What makes a test standardised

Standardized tests are not restricted to use in a school or a few schools but to larger population, so that many schools can use such types of tests to assess their own performance etc. A standardised test is a test for which content has been selected and checked empirically, for which norms have been established, for which uniform methods of administering and scoring have been developed and which may be scored with a high degree of objectivity.

A standardised test is one that has been carefully constructed by experts in the light of acceptable objectives or purposes; procedure for administering, scoring and interpreting scores are specified in detail so that no matter who gives the test or where it may be given, the result should be comparable; and norms or average for different age or grade levels have been pre-determined.

Sometimes standardised tests are misunderstood and equated with provision of norms. It is not correct. Standardisation of a test is nowadays explained in more wide terms, though norms existence is a distinctive feature of a standardised test which help in the interpretation of the results. It requires more thinking, planning, exact preparation, scoring, analysis and refinement.

It is a complex and multidimensional work. Standardised tests are those tests which are constructed by individual or by a group of individuals and are being processed and universalised for all the situations and for all the purposes.

A standardised test is widely acclaimed if its content is carefully designed, carefully phrased and simultaneously pretested. Standardised tests are prepared not for a particular local situation but for all the situations inside and outside the educational institutions. Due weightage is given to the content and objectives.

Items are to be prepared according to the blue-print. Relevant items are included and irrelevant items are omitted, giving due consideration to item difficulty and discriminating value. Internal consistency is also taken into account. Procedure of test administration, conditions for administration, time allowed for the test etc. To ensure objective and uniform scoring, the adequate scoring key and detailed instruction for method of scoring is to be provided. Adequate norms to be prepared to interpreted the results.

Test is administered over a large sample representative one. Test scores are interpreted with reference to norms. Derivation of norms is an integral part of the process of standardisation. They consist of items of high quality. The items are pretested and selected on the basis of difficulty value, discrimination power, and relationship to clearly defined objectives in behavioural terms. As the directions for administering, exact time limit, and scoring are precisely stated, any person can administer and score the test.

Norms, based on representative groups of individuals, are provided as an aid for interpreting the test scores. For effective evaluation, standardized tests need to have reliability and validity. Consistency is integral to standardized testing. Questions on standardized tests are usually objective, such as multiple choice or true and false.

This allows for easy and efficient computer grading. Although not as common, short-answer or essay questions may be used. All students receive the same prompt on these standardized tests. Essay and short-answer questions require more time and manpower for grading. Trainers teach graders to have consistent grading using a standardized rubric. Along with consistent questions, the administration, scoring and interpretation of the test must be standardized.

One style of standardized test is norm-referenced. These tests compare a student with all the other students who took the same test. Most states use norm-referenced tests because they provide a clear ranking. Uniplaces is an accommodation provider with a large choice of verified rooms, entire flats and residences.
