Introduction
The aim of tutors book, created during Leonardo da Vinci programmespilot project No. LT/01/B/F/PP-137 011 OPTIMISATION OF VET PROGRAMMES FOREMPLOYABILITY ENHANCEMENT, is to give an methodological assistance forteachers, who are designing training programmes and modules. According tothe needs of the present labour market, taking into consideration tendencies inauto-mechanics sector and analysis of the training programmes, partners ofthe project structured parameters for the vocational training modularprogramme. Composed and structured 8 modules are presented in this tutorsbook:
1. Chassis.
2. Transmission.
3. Engine.
4. Engines management systems.
5. Motor body.
6. Motors management systems.
7. Motors electronic systems.
8. Supply systems. Diagnostics repair and maintenance.
During the project were designed and tested 3 of these modules:
1. Chassis. Diagnostics and repair.
2. Transmission. Diagnostics and repair.
3. Engines management systems.
According to the designed modules samples it is possible to design all theother modules.
Completely designed module of Chassis. Diagnostics and repair is rubri-cated to the 16 themes. For every theme are planned standards, which will helpfor the teacher to set training demands for the students: training goals, trainingobjects, training content, training strategies, resources, assessment plans (speci-
fications, ways of assessment) and final assessment of module test.

Using this model of structured modular programmes, teachers will be ableto design and complete others auto-mechanic sectors modules.
Tutors books methodological information was designed for vocationaltraining teachers assistance in Lithuania and in EU countries.

Conclusions of the comparative analysis:
1. In their general features the teaching programmes under analysis andstandards are similar. This is particularly well illustrated by the fol-lowing parameters: programme duration (3-3,5 years), vocational edu-
cation level (ISCED 97 level 3), entrance requirements (basic secondaryeducation 9, 10 years).
2. The content of competences in the programmes under analysis is rathersimilar. German vocational education and training programmes distin-guish themselves by comprehensive and accurate technical motor ve-hicle occupational knowledge and skill descriptions which provide moreinformation about the content of motor vehicle qualification.
3. Motor vehicle specialisations in the analysed programmes are also rathersimilar. A general feature is intention to train specialists of broad quali-fication in motor vehicle vocational education and training programmesand standards in all the countries. Motor vehicle mechanics can workwith vehicles of various types cars, trucks, and motorcycles.
As Lithuanian partners included into their analysis training programmesfor preparation of the specialists for agricultural machinery service andrepair in agricultural schools, their analysis indicates this specialisation.
Finnish partners indicated racing cars technology specialisation.
4. The ration of theoretical and practical training is similar in all theprogrammes under analysis: theoretical training takes up 30% on aver-age, whereas practical training - 70 % of the whole training time.
5. Localisation of practical training differs. In Lithuania, the larger part ofpractical training is provided in school workshops. Company involve-ment in this area is comparatively low. In Germany, practical training
is provided on the job place in companies and, in addition, in trainingcentres founded by the companies (berbetriebliche Berufsbildungssttten).In Finland, practical training is provided in local motor repair work-shops (garages).

ASSESSMENT
Learner knowledge and skills are assessed using formal evaluation meth-ods. It is suggested to evaluate during the module and perform summative
evaluation having completed the module. Practical task, independent work,discussion, questionnaire methods are recommended for assessment in the learn-ing process. Having completed the module, a learner has to perform Test 1.
TEACHING AND LEARNING OUTCOMES.
Having listened and practically tested the practical tasks presented in themodule topics and after Test 1, the learners will be able to:
1. To select motor vehicle chassis diagnostics measures and use them safely.
2. To communicate with customers successfully, work in teams, receiveorders, identify prices for services, ensure the storage of the customersproperty.
3. To perform chassis diagnostics and repair, i.e. to identify chassis faults,to replace improper units and parts.

CORE SKILLS AND ABILITIES
The development of core skills is one of the most important tasks todaywhile teaching and learning the module Diagnostics and repair of chassistechnical state. During this module communication skills, work with others,
native language culture, computer literacy, cooperative work and problemsolving skills are developed.
MODULE MAINTENANCE AND EVALUATION.
Having completed the module, it is necessary to overview it, as the teach-ing methods and assessment can change, new diagnostic equipment can ap-pear or new students can come to learn.
During the overview, it is recommended to take into account the remarksand suggestions provided by the learner who has completed the module, thetrainer, customer or employer.
