Valrasha, observed test are only used for court ordered test or for a DOT test 'with cause', ie they caught you substituting some how or tampering with a previous test. For pre-employment test, I only know of 1 time in litterly thousands of post I've read, that a employment test was observed. That was a poor soul that had a test for a pizza hut delivery job done at a rehab center, TASC. N2
