One does not become a Proofreader / Editor overnight: enjoying reading and having a good spelling is not a sufficient condition to have the capacity to proofread or edit.
Proofreading / Editing is about enhancing the overall quality of a written text prior to its release, with regard to its form (spelling, grammar, syntax, punctuation, tyography and style) as well as its content (structure, clarity, consistency and accuracy) while respecting the original goals and style of the document; editing can also be providing authors with critical reading and writing support, in order to enhance their work according to their own ideas and style.
A French Professional Proofreader / Editor must: master French language a well as typographical
conventions; have superior writing skills and flexible writing style; adopt a sensitive and
thorough approach; have both an open and critical mind, a broad general knowledge; adapt her / his skills to
the diversity of documents; have followed specialized studies and training; possess a real
expertise as well as a solid and diverse experience in proofreading / editing; and carry out her / his work under strict confidentiality.
