Research Results

Classroom research and teacher observation show that the SIPPS® Intervention program is highly effective for a broad range of students.

Grades K–3 Outcome Data

  • The SIPPS® program was evaluated in a comparative study in California. Students using the SIPPS® program showed significantly greater gains in decoding on a normed assessment test.
  • Across all classrooms, low SES students fared better with the SIPPS® program.
  • In the SIPPS® classrooms, ELL students improved even faster than English speakers.

Grades 9–12 Outcome Data

  • With high school students, the SIPPS® program is also more effective.
  • In 2004, it was used in a summer program for struggling readers.
  • At the end of the six-week session, the average decoding gain was 12.5 standard score units in both sight-word and decoding efficiency. This was more than three times the gain found in 2003 when a different program was used.
