The latest CareerBuilder survey shows that almost one third of all employers have increased their educational requirements in the past five years. As an example, over one fourth of employers are hiring those who have master's degrees for positions which were previously held by 4-year degree holders.

Furthermore, employers are now hiring 37 percent of employees with college degrees for positions that were held primarily by high school graduates.

The survey was conducted online by Harris Poll on behalf of CareerBuilder starting from November 4 and ending on December 1 last year. Survey researchers conducted the poll nationwide and asked the inputs of 2,300 HR and hiring managers belonging to the private sector.

Based on the survey, employers increased their educational requirements for would-be-hires mainly for middle-skill jobs: 46 percent for entry-level or low-skill positions, 61 percent for middle-skill jobs, and 43 percent for high-skill work.

Employers are now hiring college graduates for positions that were previously held by high school graduates. About 60 percent of these employers said that these positions have evolved and now need higher educated manpower, while 56 percent said they do so because of the tight job market.

Employers have resorted to this practice since they enjoy its positive results. They found out that their productivity has improved 43 percent, the quality of work has improved 57 percent, communications also improved by 38 percent, employee retention was enhanced by 32 percent, and many more accrued benefits.
