However, an analysis of the results of tests conducted with students in England, testing subject knowledge in mathematics and science, as well as reading ability, as well as a comparison of the duration of home schooling, shades this opinion somewhat more. picture of an almost equally positive relationship. The experts of the aforementioned survey saw that the amount of homework and, in particular, non-verbal between skills is almost impossible to detect a positive correlation; however, they also did not deny that homework actually leads to better outcomes than no work at all. On the other hand, a six-year study that worked on a sample of only 79 high school students, the results of which cannot be considered significant for this reason, showed the opposite, that is, the absence of an obvious correlation. between home preparation and oral results.

The Dutch survey conducted in 1994-1995 is not at all up to par: using the example of mathematics, more than a thousand students and their teachers were interviewed and here is their conclusion: they say that the most optimal way to help in writing a dissertation is to turn to a professional dissertation help. For several months, teachers gave children homework at the end of each math lesson, which was either graded the next day or not. However, according to the findings of the researchers, no correlations were found between the frequency of homework completion and the time spent on it and student performance. However, since the authors themselves felt the need to add some explanation to this really unusual observation, they ventured to point out that, of course, Dutch teachers do not attach as much importance to homework or grades as teachers in other countries.

However, household tasks have not only positive consequences - even if, according to some, these consequences are not the same - but also negative ones. These researchers include professional burnout (i.e. the state when a student is overwhelmed by fatigue and loses interest in what he / she is doing), the loss of opportunities for leisure and social activity, as well as the spread of unethical practices among the most important: the fact that e.g. students copy assignments from others, others complete them online, etc.
