A number of scientific research studies have been conducted on Waldorf education effectiveness. Below is a summary of some of them (source: Wikipedia).
- A 2006 PISA study of Austrian students found that Austrian Waldorf students are above average in science. The Waldorf students did best in understanding the questions raised by science and the ability to solve scientific problems and were also above the OECD average for their joy and interest in science.
- A 2012 study of Waldorf pupils in Germany concluded that, in comparison to state school pupils, Waldorf students are significantly more enthusiastic about learning, report having more fun and being less bored in school, more often feel individually met, and learn more from school about their personal academic strengths. 85% of the Waldorf students reported that their school environment was pleasant and supportive, compared to 60% of the state school students. More than twice as many Waldorf students report having good relationships with teachers. Waldorf pupils also have significantly less physical ailments such as headaches, stomach aches, or disrupted sleep. There was no statistically significant difference between the state and Waldorf pupils’ achievement on state examinations; this is also true when test scores are compared based on the type of high school diploma granted.
- In 2005 a UK Department for Education and Skills report noted significant differences in curriculum and pedagogical approach between Waldorf/Steiner and mainstream schools and suggested that each type of school could learn from the other type's strengths: in particular, that state schools could benefit from Waldorf education's early introduction and approach to modern foreign languages; combination of block (class) and subject teaching for younger children; development of speaking and listening through an emphasis on oral work; good pacing of lessons through an emphasis on rhythm; emphasis on child development guiding the curriculum and examinations; approach to art and creativity; attention given to teachers’ reflective activity and heightened awareness (in collective child study for example); and collegial structure of leadership and management, including collegial study. Aspects of mainstream practice which could inform good practice in Waldorf schools included: management skills and ways of improving organizational and administrative efficiency; classroom management; work with secondary-school age children; and assessment and record keeping.
- A 1995 survey of U.S. Waldorf schools found that parents overall experienced the Waldorf schools as achieving their major aims for students, and described the education as one that "integrates the aesthetic, spiritual and interpersonal development of the child with rigorous intellectual development", preserving students' enthusiasm for learning so that they develop a better sense of self-confidence and self-direction.
- Waldorf students are less exposed to standardized testing; such tests are generally absent in the elementary school years. Despite this, U.S. Waldorf pupils' SAT scores have usually come above the national average, especially on verbal measures. Studies comparing students' performance on college-entrance examinations in Germany found that as a group, Waldorf graduates passed the exam at double to triple the rate of students graduating from the state education system and that students who had attended Waldorf schools for their entire education passed at a much higher rate (40% vs. 26%) than those who only had part of their education at a Waldorf school.
- A major quantitative and qualitative study of senior secondary students in the three largest Steiner schools in Australia was undertaken byJennifer Gidley in the mid-1990s. It investigated the Steiner-educated students’ views and visions of the future, replicating a major study with a large cross-section of mainstream and other private school students undertaken a few years prior. The findings as summarised below contrasted markedly in some areas with the research from mainstream students at the time:
- Steiner-educated students were able to develop richer, more detailed images of their 'preferred futures' than mainstream students.
- About three-quarters were able to envision positive changes in both the environment and human development; almost two-thirds were able to imagine positive changes in the socio-economic area;
- They tended to focus on ‘social’ rather than ‘technological’ ways of solving problems;
- In envisioning futures without war, their visions primarily related to improvements in human relationships and communication through dialogue and conflict resolution rather than a 'passive peace' image;
- 75% had many ideas on what aspects of human development (including their own) needed to be changed to enable the fulfilment of their aspirations. These included more activism, value changes, spirituality, future care and better education;
- In spite of identifying many of the same concerns as other students – global-scale environmental destruction, social injustice and threats of war – most of the Steiner students seemed undaunted in terms of their own will to do something to create their 'preferred future';
- There were no gender differences found in the students’ preferred futures visions or in the richness and fluidity of their creative images.
- A study comparing the drawing ability of children in Steiner/Waldorf, Montessori and traditional schools concluded that "the approach to art education in Steiner schools is conducive not only to more highly rated imaginative drawings in terms of general drawing ability and use of color but also to more accurate and detailed observational drawings," while another study found that Waldorf pupils average higher scores on the Torrance Test of Creative Thinking Ability than state-school students.
- An American study found that Waldorf-educated students scored significantly higher on a test of moral reasoning than students in public high schools and students in a religiously affiliated high school. Waldorf students were also far more likely to volunteer opinions about the survey and research in general, suggesting possible improvements in the survey technique and offering alternative ways of resolving the moral dilemmas raised in the survey.
- In 2006 studies have found Waldorf pupils to have a lower incidence of allergies and allergic-like symptoms, an effect which correlated with the extent to which they lived an "anthroposophic lifestyle" generally - in particular with reduced use of antibiotics, and antipyretics.
- The Thomas E. Mathews Community School in Yuba County, California serves high-risk juvenile offenders, many of whom have learning disabilities. The school switched to Waldorf methods in the 1990s. A 1999 study of the school found that students had "improved attitudes toward learning, better social interaction and excellent academic progress." This study identified the integration of the arts "into every curriculum unit and almost every classroom activity" of the school as the most effective tool to help students overcome patterns of failure. The study also found significant improvements in reading and math scores, student participation, focus, openness and enthusiasm, as well as emotional stability, civility of interaction and tenacity.
