Because standardized tests hold bias in race, culture and gender, The Skylight School for Justice will implement a portfolio evaluation system. The Skylight School for Justice wants students to be able to demonstrate their growth and take pride in what they have learned and what they are able to produce. Portfolio assessment enables measuring high-level skills with meaningful and realistic activities for students instead of measuring low-level skills in a limited-time, using multi assessment methods instead of using only one measurement method, making assessment not sometimes but continuously, and determining the student’s weaknesses and strengths. It also encourages students to participate in the assessment process actively and to make effective communication with her teacher and parents. As portfolio assessment places students at the center of the teaching process, it enables students to direct teaching.
