Same-sex parenting is a subject that is becoming extremely popular in the media, medicine and science. Homosexuals become parents. One of the reasons is the appearance of a large number of new reproductive technologies. Because of that, both gay fathers and lesbian mothers, can become biological parents of their children. Same-sex families are very diverse so we have to analyse the parenting of both fathers and mothers. Still, adoption is the most popular way for homosexuals to become parents. But, in most countries – including Croatia, adoption by same-sex couple is not legal. Reason for that are the stereotypes that are empirically questionable. Because of that, a large number of both qualitative and quantitatve research has been conducted in past years. They analysed the impact of same-sex parenting on personal, social, psychological and cognitive development of children. In the beginning, research was criticized because it was conducted on a small sample of same-sex parents and children and there were no longitudinal studies available. Today, studies have improved and their results are of great importance for every field that deals with same-sex parenting. One of these fields is the school which also has a great impact on children of same-sex parents. It is important that schools cooperate with parents in order to avoid any unwanted consequences and ensure inclusion. This MA thesis also includes comments of children raised by same-sex parents - that are considered the most important factor for evaluating the quality of same-sex parenting.
