Any information, materials on defining nutrition core competencies and a national nutrition training program?

Does anyone have any national-level examples where: 1) Nutrition competencies have been clearly defined for both in and pre-service training? 2) Any country examples where a national nutrition strategy has evolved into a national nutrition training strategy that has looked at pre-service, in-service, continuing education, communications materials, and strategies to train different cadres of workers including: frontline health workers, agricultural extension officers and/or professional cadre of nutritionists/dietitians? 3) any other information that would help to think of a comprehensive national training model for nutrition that is mult-sectoral and works for different levels of training (prefessional vs. frontline vs. volunteer) THANKS
