Marshall was quoted by the Dallas Morning News as stating, “Almost every indication of TEI has been successful.” The News also stated, “Current DISD data shows the district’s retention rate (85.08 percent) is better than the state’s average; of the teachers at the highest performance levels, 93 percent were still at their campuses.”
The turnover rate since implementing TEI has increased every year. The Texas Education Agency states that the most recently reported teacher turn-over rate in Dallas ISD is 21.6% putting the teacher retention rate at 79.4%.
Currently, 44% of DISD teachers have less than 5 years of experience.
These indications show that TEI has not been successful in our efforts to improve our school district.
