5 possible reasons for HIGH-passing-rate trend in BAR exam

The passing average is the minimum grade in the exam required to be admitted to the practice of law. The passing rate is the proportion of total number of bar passers in relation to the total number of bar examinees. It is usually computed on two levels—the national level (national bar passing rate), and the law school level (law school passing rate). In the past, passing averages were considerably lower to admit more new lawyers (i.e. 69% in 1947, 69.45% in 1946, 70% in 1948). Since 1982, the passing average has been fixed at 75%. This has led to a dramatic decrease in the national passing rate of bar examinees, from an all-time high of 75.17% in 1954 to an all-time low of 16.59% in 1999 (all-time low should have been the single digit 5% national passing rate for the 2007 bar examination if the Supreme Court did not lower the passing average to 70% and lowered the disqualification rate in 3 subjects). In recent years, the annual national bar passing rate ranges from 20% to 30%. (Bar Passing Percentage from 1946-2003. The Practice: Business & Leisure Magazine for Lawyers. August–September 2004 Issue.) [1] Probably, many lawyers have recently been disbarred or have died.
[2] Probably, the Supreme Court is trying to pressure law schools over the country to be more strict in allowing law students to graduate.
[3] Probably, more lawyers are needed because of the rising number of complaints due to e-commerce. A recent study has found that, all over the world, the Philippines ranks 89th in the world of e-commerce.
[4] Probably, the Supreme Court is simply following a cycle since this already happened decades ago.
[5] Probably, this is one of the strategies of High Court, alongside with the e-filing system and the new speedy trial rule on criminal cases, to help de-clog court dockets.
