From the web sources I could receive the following information related with HSST commerce, Since I am a commerce post graduate and one of those who appeared in that Exam, I made a clear watch in the situation of HSST commerce. The information received and known to most of us.
The exam was conducted on 27/6/2012 at 8 am. The no.of candidates appeared for Exam is 4302. The exam was conducted for 3 posts namely HSST Senior, Junior and NVT commerce combined. The exam conducted i 2006 was separate. The cut off for each was nearly 67 and 66. The senior HSST and junior list contained less than 400 candidates in the main list.
Some general facts related with cut off of any standard objective test is as follows:
1] The cut off is related with many factors like number of available post and number of candidates sanctioned to be included in the list. Here it is said that 1000 candidates are proposed to include in the list of HSST. The easy level/ difficulty level of question paper, the number of questions omitted, the relative and individual intelligent capacity and knowledge, emotional and competitive level of candidates also plays a role in the cut off position
2] For common exams like university exam, other qualifying test, 35% is the standard pass mark. Now it is relieved as D+ grade or 30%. The logic behind this is the statistical laws of distribution. A standard test with 50% difficulty/easy level of question will cause a 50% to pass when 35% is taken as cut off. Suppose there are 5000 candidates for such a standard test, considering other factors are normal, the number of passed will be 2500 when 35% is the pass mark. If 5% marks is more reduced ie. 30% is the pass mark,like the present SSLC and HSC Exam a 20 m0re % ie 70% will be passed. The present SSLC and HSC takes 90% because of the moderation and out of low difficulty level and liberalized valuation. This is about all tests and without negative scoring. The PSC Exams are with negative marks and so there needs some more calculation. In any of test the number of candidates in upper 15% and lower 15% will be very less or negligible. That means only few candidates get above 85% or below 15%. Thus in a distribution of 100%. when taking those upper and lower percentage, it becomes total 70 and the average is (85-15)/2= 35, and so 35% is the standard pass mark
Analysis of cut off for HSST
No.of questions or Maximum mark to be achieved- 91.
Normal rule of objective type test withot negative mark: 60% of candidates will be below 40% and 40% of students will be above 40% (40 to 100%). But for KPSC only 1/3 negative ie. a candidate get lessened one full mark for only 3 mistakes. So the normal law cannot be taken as cent percent here. A modified law of 65% of candidates will be below 45% can be adopted here.
40% of the total 91- 36
65% is below 37 marks mean 35% will be above 36 marks. It means there will be 1505 candidates in HSST exam having marks above 36.Again on a scientific manner if it is distributed we can get the following table.
Class------------------- No.of candidates
In higher mark area, the no.of candidates will be low and towards lower the number of candidates will be high. But in the very lowest area ie, 0 to 15% class it is again the number of candidates will be low. From the above it is clear that 40 is the cut off when 1000 number of candidates are selected. Don't forget it is based on the following assumption
1. The test was a standardized test. But it was a biased one contained a positive skewness towards questions in marginal costing
2. The difficulty/easy level of question is average and lies between 45 to 55%. But HSST test was considered as more difficult for 75% of students and so this factor may reduce the cut off
3. There is no malpractice. If malpractice has taken place, a good percentage of students will get high marks and this will cause a rise in cut off
4. The intelligence level of candidates is normally distributed. This indicates the number students with huge preparation and without preparation is almost same. When all students are brilliant and competent and prepared to get 90% of marks, the cut off will automatically rise. But the situation for HSST was normal`
OK wish you all the best. If you have any doubt or opposition in my opinion or to add anything please post it
This is based on keeping other assumption
