However, he added, "there's no paperproduction, and students can walk out of the testcenter with an unofficial score generated by thecomputer."

An official score is available within 10 to 14days of the test date.

In general, Johnson said, "ETS is finding thatthe GRE CBT is more user-friendly, and they'remaking a better profit on it."

Johnson said the cost of taking thecomputer-adaptive GRE is about $100, an increasefrom the cost of taking the paper-based test.

ETS's biggest concern with the newcomputer-based testing system is the possibilityof not having enough computers to satisfy demand,said Johnson.

But in the wake of the successfulcomputerization of both the Test of English as aForeign Language (TOEFL) and the GraduateManagement Admission Test (GMAT), ETS officialsseem primed for another smooth transition.

In a letter published on ETS's Web site, ETSVice President for Graduate and ProfessionalEducation John Yopp said he thinks computer-basedtesting has enormous potential.

"[By applying computer technology to testing]we can now measure how content is applied inproblem-solving and reasoning exercises," heexplained
