In Canada and the United States, writing tutor is the common term used for individuals working one-on-one with students in college and university writing centers.   The terms tutor and consultant are often used interchangeably, and both terms are used with deliberation as they are seen to represent a specific relationship, role, or activity between tutor and tutee. For example, Griffin, Keller, Pandey, Pedersen, and Skinner  in their 2003-2004 survey of North American writing centers describe a tutor as an expert providing a less expert learner with knowledge, implying a transmission approach. In contrast, the consultant, also expert, collaborates with the tutee in addressing the writing task, implying a social constructivist approach. The focus of the social constructionism paradigm is to get rid of the idea that tutors are an authoritarian figure instead of someone who the student can collaborate with. Social constructionism is the dominant approach used in writing centers today versus the expressivism approach that was favored in the 1970s and 1980s.  Others who use the term writing tutor describe the tutor as facilitating learning through active listening, responding, as well as using silence and wait time.  Taking the cue from the student, these writing tutors function much like the consultants described by Griffin et al., offering suggestions and working together on a given writing task. Regardless of the title, the intent and actions of the tutor are important to writing center practitioners. A tutor may say he/she is acting collaboratively with the student and unknowingly be enforcing her or his own agenda. 
At Superprof, we offer more than 1000 subjects across dozens of categories (sports/ academia/hobbies/music/etc.). You don’t necessarily have to be a qualified tutor to be an effective educator. For example, a professional pianist is obviously qualified to give piano lessons but teaching involves much more than certification. It requires passion; love for your craft, enthusiasm and the ability to foster these attributes in your students. A piano teacher does not necessarily have to be a concert pianist, but they must have good ideas on how to become one and how to master the instrument and the music.
