A biofilm is any group of microorganisms in which cells stick to each other and often also to a surface. These adherent cells become embedded within a slimy extracellular matrix that is composed of extracellular polymeric substances (EPS).
Career Requirements. Kindergarten teachers in public schools are required to have at least a bachelor's degree in education and teacher certification for the state in which they work. Certification typically requires candidates to complete student teaching requirements and pass any required professional exams.
Bachelor's Degree. Kindergarten teachers receive training similar to that of other elementary school teachers. In all states, public school teachers need a minimum of an accredited bachelor's degree, normally in early childhood education. Private schools set their own requirements but usually require a bachelor's degree.
