What is benchmark in Levelling?

The creation of both types of benchmark scores involves reverse coding items where necessary and converting all responses to the same scale. … College, campus, and group- level benchmarks can be calculated by computing the weighted average of the individual benchmark scores, either raw of standardized.

How do you calculate RL in surveying?

8 Rise and Fall Method This method consists in finding the difference of level between consecutive points by comparing each point after the first with that immediately preceding it. The reduced level (R.L.) is found by adding rise of subtracting fall to or from the preceding reduced level itself (R.L.).
